Frontogenesis and Frontolysis; Cold, Warm and Occluded Fronts

Air mass is a volume of air defined by its temperature and water vapour content. An air mass may be of many hundreds or thousands of square miles, and adopt the characteristics of the surface below them. An air mass ..

Types of Rainfall: Convectional, Frontal, Orographic Rainfall

The amount of moisture in air is commonly recorded as relative humidity; which is the percentage of the total water vapour air can hold at a particular air temperature. The presence of warm, moist and unstable air and sufficient amount ..

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 ..
