Atmospheric pressure

The atmosphere has a mass of about 4.5 to 5.0×1018 kg. The atmospheric temperature, pressure and density vary considerably with altitude. The atmosphere surrounding the Earth from dangerous cosmic radiations from outer space and helps in sustaining life on the earth. The atmosphere plays a vital role in maintaining the heat balance on the earth by absorbing the infrared radiation received from the sun and re-emitted by the earth. Infact, it is known as “the greenhouse effect”, which keeps the earth

According to the American Meteorological Society, a meteorologist is an individual with specialized education who uses scientific principles to explain, understand, observe or forecast the earth's atmospheric phenomena and/or how the atmosphere affects the earth and life on the planet. In basic terms, a meteorologist is someone who observes, reports, and forecasts weather conditions. Most people are familiar with the meteorologist they see on television or hear on the radio, but most meteorologists

bub Weather is the state of the atmosphere at a given time and place, with respect to variables such as temperature, moisture, wind velocity, and barometric pressure. Weather can be classified as day to day temperature and precipitation activity, where climiate is average atmospheric conditions over longer periods of time. Weather occurs from temperature and moisture differences between one place and another. These differences can occur due to the sun angle at any particular spot. The strong

mixes with the water and creates a moisture in the air creating a low pressure system. A high pressure system is created when the cold water reduces the air above it. During a low pressure system the air becomes moist and can create severe tropical storms, on the other hand when there is a high pressure system the cold dry air goes back down and takes away all of the moisture. When combined this can create a high and low pressure forcing the wind in the atmosphere to blow low and the higher air blows

is a complex sequence of natural climate variations that take place in the tropics of the Pacific Ocean, yet affect the climate of the entire globe. The climate phenomenon, known as ENSO, has three main phases that each differ markedly in their atmospheric and oceanic conditions. El Niño, also known as “the warm phase”, is the first cycle that begins when warm water in the eastern Pacific Ocean shifts to the west toward South America. During El Niño, the east-to-west trade winds halt and sometimes

This experiment will be highlighting the significance of atmospheric pressure in a cloud`s formation. Clouds form when warm, moist air rises in the atmosphere. On its way up, it cools so that the water vapor condenses into small particles such as airborne dust, thereby forming water droplets. This is exactly what a cloud is, a large collection of very tiny droplets of water or ice crystals. This process is known as cloud formation and is affected by temperature since clouds are occasionally produced

The Effect of Climate Change on Natural Disasters What is climate change? According to Dictionary.com climate change is: “a long-term change in the earth 's climate, especially a change due to an increase in the average atmospheric temperature”. The increase of the Earth 's surface temperature is largely due to the effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforesta-tion. These emissions are what traps heat onto the Earth’s surface, which, in

the biological and physical procedures around the world. The sun is capable of producing heat; as a result the sun heats up the air as well as the surrounding atmosphere, allowing for change in the weather. Climate being the long-term pattern of atmospheric conditions, we must analyze weather statistics over a large span of time, in order to determine climate change. As we know, the earth constantly orbits around the sun changing its position frequently from time to time. It is said that this orbital

Earth is living and breathing planet, it takes a lot of energy to keep the Earth health, to keep all its inhabitants functioning. Earth is a special planet because it is the only know planet that can allow life to thrive. Earth receive a tremendous amount of energy from the Sun, solar energy is necessary for life on Earth. A planet filled with life needs water, it is one of the essential pieces for all humans, animals, and plants. Earth is cover primarily by water, a unique substance that keeps
