The most powerful force which causes air to rise and cool is the Sun. When the Sun heats the surface of the Earth, warming of the air above the ground takes place. This warm air rises and cools as it goes higher. At a certain point, condensation will occur and clouds will form.... read more ›
That force is 'gravity'. Gravity's role is its pull of cooler, denser air toward the earth's surface. As the denser air reaches the earth's surface it spreads and undercuts the less dense air which, in turn, forces the less dense air into motion causing it to rise. This is how hot air ballooning works.... see more ›

Sometimes, cool air rises and warm air sinks — and that helps the tropics cool off.
Known as the "vapor buoyancy effect," this phenomenon renders humid air lighter than dry air of the same temperature, pressure and volume.. On a grand scale, the vapor buoyancy effect helps direct the movement of air through the lowest region of the atmosphere, known as the troposphere, and particularly affects air over humid, tropical regions.. Now, a new climate model suggests that this cycle of humid air rising and dry air sinking may somewhat buffer the effects of climate change in the tropics.. While modern climate change models take this wisdom into account, Yang aimed to investigate how the humid air of the tropics influences overall warming in the region, more specifically.. In the tropics, global patterns of air circulation generate columns of humid air and columns of relatively dry air that sit alongside each other, extending skyward, Yang said.. The subsequent change in buoyancy drives the humid air upward and drives ripples through the surrounding air; these ripples, known as atmospheric gravity waves, push heat out of the humid air and into the dry air nearby, Yang said.. "In other words, [vapor buoyancy] will make the sinking dry air even warmer," allowing more heat to be emitted from clear-sky regions, Yang said.. "If we don't have this vapor buoyancy effect, it would likely be the other way around," meaning that the increasingly warm air would rise in humid regions where its heat would be trapped beneath clouds, he added.

Cumulus clouds are often a sign of good weather but when cumulus clouds are filled… The suffix “nimbus ” used in naming clouds means.. Turbulence occurring in convective storms particularly thunderstorms that is felt by aircraft .. A cumulus with little vertical development means you can expect some turbulence.. However a towering cumulus cloud means you can expect very strong turbulence.… •Low clouds: There are 4 types of low clouds:. thunderstorm a violent short-lived weather disturbance that is almost always associated with lightning thunder dense clouds heavy rain or hail and strong gusty winds.. – Stratocumulus are layered cumulus clouds.. These are created as a result of the differences occurring within the densities and temperature of a specific gas or a fluid.. Changes in weather are another cause of turbulence.. Nimbostratus clouds are formed when warm moist air is gradually lifted over a large area typically produced by a warm front.. Cumulonimbus clouds are thunderstorm clouds.
Vital Signs of the Planet: Global Climate Change and Global Warming. Long-term effects of global climate change in the United States.
Global climate change is not a future problem.. In fact, according to the Intergovernmental Panel on Climate Change (IPCC) — the United Nations body established to assess the science related to climate change — modern humans have never before seen the observed changes in our global climate, and some of these changes are irreversible over the next hundreds to thousands of years.. So, the Earth's average temperature has increased about 2 degrees Fahrenheit during the 20th century.. The severity of effects caused by climate change will depend on the path of future human activities.. Heat waves, heavy downpours, and sea level rise pose increasing challenges to many aspects of life in the Northeast.. Sea level rise, erosion, flooding, risks to infrastructure, and increasing ocean acidity pose major threats.. The warming climate has also caused a decline in water supplies, reduced agricultural yields, and triggered heat-related health impacts in cities.
Global Warming and the Water Cycle
Global Warming and the Water Cycle. The images and questions below address some of the interdependent relationships between global warming and the water cycle.. Currently, about 2% of the water in the water cycle is temporarily out of this loop, because it is trapped in ice.. Also, water expands as it gets hotter, so as the oceans warm up, the water in them takes up more space.. There would be less water on and in the ground just when hot weather was increasing water demand.. Most seriously, decreases in groundwater and surface water supplies and increases in demand due to the heat mean that there may not be enough clean, fresh water to meet the need for irrigation and even drinking water.. Also, global warming raises sea level, because ice melts and liquid water expands when temperature rises.. You have seen how global warming can influence the water cycle.. Describe ways in which you think the water cycle could affect global warming, and reinforce or diminish temperature change.. Many of the questions raised in this endeavor have no absolute answers.There are several ways that the water cycle could accelerate global warming.
Climate change will likely make extreme weather events more common. Some types of weather are easy to attribute to climate change. But with tornadoes, things are a bit more complicated.
Tornadoes have been recorded all over the world, but the United States experiences around a thousand of them each year, which is far more than anywhere else on the planet.. Climate change has also caused an increase in extreme weather events all over the world.. Predicting whether climate change will have an effect on the frequency and power of tornadoes is a challenge.. This makes them very difficult to model in the climate simulations that scientists use to project the effects of climate change.. Instead, scientists must attempt to predict how climate change might affect the individual weather “ingredients” that support the development of supercell thunderstorms (the type that produce tornadoes).. Climate simulations can help scientists predict what effect climate change might have in the future.. In fact, when you remove small tornadoes from the record, the data does not suggest any long-term increase in tornado frequency.. Other types of extreme weather, such as Tornadoes, are also exhibiting changes which may be linked to climate change, but scientific understanding isn’t detailed enough to project direction and magnitude of future change.” In other words, we still have a lot to learn about how climate change might affect tornadoes.. One thing we know for certain is that we live in a warmer, wetter world thanks to climate change, and this is likely to have an effect on extreme weather events, including tornadoes.
As we live closer together and push global boundaries, experts believe we need to be more prepared for the next infection that may spread into a pandemic.
Public health experts believe we are at greater risk than ever of experiencing large-scale outbreaks and global pandemics like those we’ve seen before: SARS, swine flu, Ebola and Zika.. The facts around urban living are simple: You live, eat, work and move closer to people than in any rural setting, and with this comes greater opportunity for diseaseto spread through air, mosquitoes or unclean water.. Beyond people’s close proximity, “this is a second source of infection,” he said, and a third is increased food demand, causing farmers to grow more food, with more animals, making them likely to live closer to those animals as well.. With people moving more regularly from – and between – rural settings to urban ones, the chances of them becoming infected and then living in close quarters with others further boosts the potential for things to spread.. Heymann explains that Lassa is one example of people living near forest environments where infected rodents reside, but destruction of those forests for agriculture leaves the animals nowhere to go – other than humans’ homes.. Whitworth cited the current yellow fever outbreak in Angola, which has infected more than 350 people.. According to experts, infectious agents can live in humans during their incubation period -- the time between infection and the onset of symptoms -- meaning that travelers can transmit an infection to another region even though they don't appear to be sick.. If a country is on the brink of breakdown from civil unrest, its ability to handle an intense and sudden outbreak could bring its people to their knees -- and allow the infection to flourish.. An incubation period is the time between infection and the onset of symptoms, meaning people can transmit an infection though they won’t appear to be sick.. More than 8,000 other people became infected across more than 30 countries worldwide.. But if a country is on the brink of breakdown from civil unrest, the ability to handle an intense and sudden problem like an outbreak could bring its people to their knees – and allow the infection to flourish.. That problem combined with humanmovement between these three countries and others more globally meant Ebola was able to spread, even though dozens of infections in previous years in nearby Democratic Republic of Congo were self-contained and often resolved themselves.. Beyond weak health systems, countries where outbreaks are more likely to occur – namely, more developing settings – also have fewer doctors and nurses to treat the population.. Heymann describes the likelihood of a new infection spreading rapidly and becoming an epidemic – and potentially a global pandemic – using the analogy of lining up pieces of Swiss cheese, with the different risk factors equating to holes in the cheese.. It’s aiding the development of vaccines against viruses that it believes need attention and are in families of infections that are likely to pose a risk, such as MERS CoV, which continues to persist in the Middle East and has been reported in almost 20 countries outside that region.
The day Christ will return because God specifically chose not to reveal this to us but we should still remain close to Scripture so we know what signs to look for.
The Rapture is an End Time’s event where Jesus Christ returns for His Church.. Only God knows the date, the time and the hour, and only God knows when time will run out.. At the time of the Rapture, believers who have died will have their bodies resurrected and, along with believers who are still living, will meet the Lord in the air.. While the Rapture and the Second Coming of Christ are similar, they are separate events.. In the first stage of the Rapture, the Lord comes for His church; whereas, at the end of the tribulation period, He comes back with His church.. At this event “every eye shall see Him” although at the Rapture he will come “as a thief” and only believers will see Him.. There will be many people who will claim to be the Messiah and also claim to have the answers for a troubled world.. In this passage Jesus, speaking to us, warns us that false prophets will rise and show great signs and wonders to deceive, if possible, even elect.. A major sign of Christ’s return is war and dissension among groups of people which is something we see happening right now.. Many wonder what all the world’s current devastation might be telling us.. The pre-tribulation view is that the Rapture will happen before the tribulation period, the mid-tribulation view is that the Rapture will occur half-way through the tribulation period and the post-tribulation view is that the Rapture will occur at the end of the tribulation period.. However, whether to live to see pre-tribulation, mid-tribulation or post-tribulation or we die prior to any type of Rapture at all, they key to eternal salvation in all cases is our faith in Jesus Christ alone.. Though we won’t be condemned for our sins, our present lives do affect what will happen at the Judgment Seat of Christ.. Though we won’t know the date, time or hour of the Rapture and Jesus’ Second Coming, we can be aware of all that is going on around us so that we are living the life God intended for us in Christ.. Her father, a Lutheran pastor and life coach was a big influence in her faith life, helping her to see the value of sharing the message of Christ with others.
This is the most dangerous stage of the storm and is the most likely time for hail, heavy rain, lightning, strong winds and tornadoes.. Even though hail is not common to the state, there have been about a dozen events of hail of over 3 inches being reported in Florida.. The source of the damaging winds is the downdraft within the thunderstorm.. The most common type of flood that happens during a thunderstorm is a flash flood.. Most lightning forms at the bottom of the cloud, though less than 5% of all lightning occurs from the top of the anvil, making it a positive lightning strike.
The coronavirus pandemic is forcing changes big and small to the economy, to society, even to the trajectory of young lives. Harvard experts weigh in on some key areas.
Unlike shocking events that punctuated recent generations — the Kennedy assassination, or the Challenger disaster — the pandemic packs a more enduring punch, affecting nearly every aspect of life with its long duration and widespread personal impacts like the deaths of loved ones and losses of jobs and businesses.. Though many will eventually return to the office, Tsedal Neeley , Harvard Business School ’s Naylor Fitzhugh Professor of Business Administration, said the shutdown highlighted the ease with which modern technology handled the shift from one location to another, as well as the ability of many office workers to get the job done even when not under their manager’s eye.. “I don’t think remote work will be permanent at the scale we saw in March, but I have no doubt that remote work will increase,” said Neeley, whose forthcoming book is “Remote Work Revolution: Succeeding from Anywhere.” “We’re definitely going to see a much bigger population working remotely.”. Not only has it already transformed the workdays of millions, it could create a self-perpetuating cycle, as more workers become familiar with the virtual tools needed to work remotely and organizations change to accommodate those working out of the office.. In July, Google announced that those whose functions don’t require them in the office can work from home through July 2021 and, as the pandemic has stretched into the fall, other companies, like Microsoft and Ford Motor Co., have said offices will be closed through next summer.. Online retail giant Amazon, on the other hand, has reported record profits, while electronics seller Best Buy reported increased second-quarter sales due to online purchases driven by home office needs.. Professor of Retailing at Harvard Business School, the COVID crisis has hit different retail sectors differently.. Willy Shih , Harvard Business School’s Robert and Jane Cizik Professor of Management Practice in Business Administration, has heard the calls to dismantle the global manufacturing system.. Some manufacturers, Shih said, may decide to bring home production of essential parts, or to diversify production from one nation to multiple, which Shih called “China plus one” or “China plus two.”. The use of cash in financial transactions has long been on the decline, with the FDIC reporting in 2017 that it was used in just 30 percent of all payments, according to an article by Shelle Santana , assistant professor of business administration at Harvard Business School.. According to research by Santana and the online payments processing and financial services company Square, last spring’s shutdown led to an enormous jump in the percentage of U.S. retailers that were effectively cashless, defined as 95 percent or more of all transactions completed via credit, debit, or mobile.. On March 1, about 8 percent of U.S. retailers using Square’s payment service were effectively cashless, but by April 23 the number had soared to 31 percent.. Instead of 8 percent of U.S. businesses being effectively cashless as they were before COVID’s spring disruption, she expects the number to fall to between 12 and 15 percent.. Delbanco said people have been talking about a shift to telemedicine for 20 years, but before COVID, just 7 percent to 8 percent of care was done remotely.

Weather simply refers to the condition of the air on earth at a given place and time – whether it is warm or cold, dry or wet, blowing or calm.. A warm front forms where a warm air mass moves into a cold air mass.. When the front passes, the sky clears and the air pressure rises.. Temperatures also rise as warm air replaces cold air.. Certain weather conditions are associated with high and low pressure systems.High Pressure Areas. In a high pressure area, air is more dense than in areas of lower pressure.. The result is that air will move from the high pressure area to an area of less density, or lower pressure.. Winds blow away from high pressure areas toward areas having lower air pressure.. Winds tend to blow into low pressure areas because air, like other gases, moves from areas of higher pressure into areas of lower pressure.. As winds blow into a low, the air moves up.. Air pressure is measured by barometers.. You might not be able to see all the forms of water, but they're there.Precipitation. Wind is caused when air moves from an area of high pressure to one of low pressure.. Air temperature is measured with thermometers.. Cumulonimbus clouds are towering storm clouds that bring rain, sleet, hail, thunder, lightning and tornadoes.
