Terms to remember:

1. insolation 4. roaring forties

2. inversion of temperature 5. nimbus

3. anemometer 6. meteorology

1) Insolation: It is the solar radiation that reaches the Earth’s surface and is measured by the amount of solar energy received per square centimeter per minute.

2) Inversion of temperature: It is a reversal of the normal behavior of temperature in the troposphere, in which a layer of cool air at the surface is overlain by a layer of warmer air.

3) Anemometer: It is also called wind gauge which is an instrument for recording the speed and direction of winds.

4) Roaring forties: It is the area between latitudes 40⁰ and 50⁰ south in the Southern Hemisphere, where the prevailing winds blow persistently from the west. They have strong winds throughout the year.

5) Nimbus: It is a cloud that produces precipitation which reaches the ground as rain, hail, snow or sleet. They can be characterized by their great height.

6) Meteorology: Meteorology is a branch of atmospheric science. Here we study about the happenings in the environment around us and the reasons behind them.

Precisely it is the scientific study of weather.
