Precipitation and its types
Precipitation is any form of water particle, whether liquid or solid, that falls from the atmosphere and reaches the ground. The process of continuous condensation in free…
Tri-cellular model of atmospheric circulation
The actual global pattern of atmospheric circulation is much more complicated than a direct flow between the equator and poles. Instead of one large circulation in each…
What is a Heat Dome?
What is a Heat Dome? A heat dome is an area of high pressure that remains over a region like a lid on a pot, trapping heat….
ATMOSPHERIC PRESSURE
The weight of a column of air contained in a unit area from the mean sea level to the top of the atmosphere is called the atmospheric…
Forces Affecting the Velocity and Direction of Wind
● Air is set in motion due to the differences in atmospheric pressure. ● The air in motion is called wind. ● The wind blows from high…
STRUCTURE OF THE ATMOSPHERE
The atmosphere consists of different layers with varying density and temperature. Density is highest near the surface of the earth and decreases with increasing altitude. The column…
COMPOSITION OF THE ATMOSPHERE
The atmosphere is composed of gases, water vapour and dust particles. The composition of the atmosphere is not static. It changes according to the time and place….
Heat Budget of the Planet Earth
The earth as a whole does not accumulate or loose heat. It maintains its temperature. This can happen only if the amount of heat received in the…
Factors Controlling Temperature Distribution
Temperature The interaction of insolation with the atmosphere and the earth’s surface creates heat which is measured in terms of temperature. While heat represents the molecular movement…
Variability of Insolation at the Surface of the Earth
Solar Radiation ● The earth’s surface receives most of its energy in short wavelengths. ● The energy received by the earth is known as incoming solar radiation…
