Precipitation: The water in the form of a pond or lake or the groundwater is derived from the precipitation. The term precipitation is used for all the forms of water. i.e. Solid, liquid, or gaseous state of water. The economic development of any country directly and indirectly depends upon the total annual precipitation received by the country.
This has helped to have very thick, tall hard forest lands having very high density and very high plant biodiversity. Their economy mainly depends upon lumbering activities. These thick forests also have very high species biodiversity and have a variety of wildlife.
So the type, the amount and the distribution of precipitation is a very important factor to decide the fate of a country.
In India the distribution of rainfall is very uneven. Its variation also is too high to create drought conditions when it exceeds the average of floods.
Types of precipitation
On the basis of the spread intensity and total receipt the precipitation can be classified as
- Drizzle
- Rain
- Cloud burst
- Hail
- Snow
- Sleet
- Dew
- Frost
- Fog
- Smog
1. Drizzle
In this type the size of the water drops is small i.e. it is less than 0.5 mm in diameter
2. Rain
It has the bigger size of the water drops i.e. more than 0.5 mm in diameter.
3. Cloud burst
It has a very high intensity e.g. cloudburst at morbi in gujarat.
4. Hail
It is a solid form of ice with the diameter varying between 0.5 mm and 5.00 cm . the hail storms are generally observed during the pre monsoon condition in the months of april and may.
5. Snow
It is a solid form of precipitation received in the form of ice crystals. It is observed mainly in the high altitude region like himalayas.
6. Sleet
When the ground and the atmospheric temp. Near the ground is + 0 degree celsius the precipitation is in both solid and liquid forms.
