10th Social Studies New Text Book - Climate and Weather

Climate and Weather: The state of atmospheric conditions over an area at a particular point of time refers to weather. These weather conditions fluctuate very often even in short period. Climate refers to such conditions over a large area and follows a similar general pattern over many years. What have been the general conditions, year after year, over thirty years or more, gives us the climate.

There are variations from year to year but a basic pattern remains the same. On the basis of these generalized conditions, the year is divided into seasons. The important elements of climate such as temperature (maximum and minimum) and rainfall can be shown with the help of climographs (also called ‘climatographs’). The elements of weather and climate are: temperature, atmospheric pressure, wind, humidity, and precipitation.

Climographs of a few places in India.
