Evaporation and Condensation, and so governs the degree of stability of the atmosphere. 3. As relative humidity is directly associated with the temperature of the air, it affects the character and kinds of cloud formation and precipitation. Temperature is the degree of hotness or coldness of an object. We tend to observe … Read more
An Atmosphere is a layer of gases surrounding a planet or other material body, that is held in place by the gravity of that body. Many of the planets in this Solar System have atmospheres, but none that we know of have an atmosphere quite like ours – one that can support life. The … Read more
Pressure and wind belts Atmospheric Pressure, also called barometric pressure, force per unit area exerted by an atmospheric column (that is, the entire body of air above the specified area). Atmospheric pressure can be measured with a mercury barometer (hence the commonly used synonym barometric pressure), which indicates the height of a column … Read more
Weather forecast There are two ways for weather forcasting: Short-range forecasting Meteorologists can make somewhat longer-term forecasts (those for 6, 12, 24, or even 48 hours) with considerable skill because they are able to measure and predict atmospheric conditions for large areas by computer. Using models that apply their accumulated expert knowledge quickly, accurately, and … Read more
Kinetic theory of gases The kinetic theory describes a gas as a large number of submicroscopic particles (atoms or Molecules), all of which are in constant rapid motion that has randomness arising from their many collisions with each other and with the walls of the container. According to kinetic theory of gases, the molecules of … Read more
Origin of the Monsoon: Classcial Theories: Halley’s Thermal concept: Indian monsoon is because of contrast between Indian Subcontinent and adjoining Indian Ocean. Halley’s theory, suggested in 1686, considers the summer monsoon to be a regional phenomenon. Aerological concept: This was suggested by R. Scherhag in 1948. According to this theory, monsoon circulation develops due to … Read more
The Coriolis Force: A Silent Conductor of Wind Movement The wind, a seemingly chaotic force that whips across the globe, is actually governed by a complex interplay of factors. One of the most crucial, yet often overlooked, influences is the Coriolis force. This force, arising from the Earth’s rotation, subtly steers winds, shaping weather patterns … Read more

Pressure groups and formal/informal associations and their role in the Polity Pressure groups have become a very important part of an administrative system. These groups try to pressurise the administrative and political system of a country either to ensure that their interests are promoted or to see that at least their interests are not relegated … Read more
