Monsoon Mechanism

The word monsoon derived from the Arabic word mausim means seasonal winds. In this system, the direction of the winds reverses seasonally. The first thing we note is that Monsoon is typically considered a phenomenon of tropical south Asia, but ..

List of Local Winds around the Globe

The Local winds around the world are formed through the heating of land. In coastal regions, the sea breezes and land breezes are important factors in a location’s prevailing winds. The sea is warmed by the sun more slowly because ..

Global Winds: Trade Winds, Westerlies and Polar Easterlies

When air moves in a definite direction, it is called wind. If the winds move from west to east, they are called westerlies. If they move from east to west, they are called easterlies. There are winds because there are ..

Atmospheric Pressure and Pressure Belts

Air has weight and a column of air extending vertically over a given area on earth’s surface exerts pressure. The atmospheric pressure is measured as a force per unit of area and most common unit of measuring the air pressure ..

Distribution of Temperature on Earth

Temperature differs from one part of the world to the other. Since Insolation is the basic source of energy for the atmosphere, the distribution of insolation would determine the temperature of the earth. Thus latitude, altitude, distance from sea, features ..

Earth’s Energy Budget

Earth’s Energy Budget can be discussed in terms of incoming heat energy and outgoing heat energy. These are as follows: Incoming Heat Energy This is made of : Solar radiation (99.97%) Geothermal energy (0.025%) Tidal energy (0.002%) Fossil fuel consumption ..

Role of Atmosphere in Earth Heat Balance

Sun is the major source of energy for the entire earth system. The earth does receive very small proportions of energy from other stars and from the interior of the earth itself (volcanoes and geysers provide certain amount of heat ..

Ionosphere Facts and role in Radio Transmission and Aurora

Ionosphere is called so because it is ionized by solar radiation. It plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere. Ionosphere stretches from 50 to 1,000 km and typically overlaps both the exosphere ..

Measosphere Facts

The mesosphere extends from the stratopause to 80–85 km. Most meteoroids get burnt in this layer. Temperature decreases with height in the mesosphere. The mesopause, the temperature minimum that marks the top of the mesosphere, is the coldest place around ..

Facts About Stratosphere

The stratosphere is the second major layer of Earth’s atmosphere, just above the troposphere, and below the mesosphere. It is called stratosphere because it is stratified in temperature, with warmer layers higher up and cooler layers farther down. Top of ..
