Identify the form of precipitation with the following description.

'It is frozen rain drops cooled to the ice stage while falling through air at sub-freezing temperature."

Different forms of Precipitation are as follows:

i) Rain: It is the most common form of precipitation. In this the water droplet size are larger than 0.5 mm and smaller than 6 mm.

On the basis of intensity, rainfall is classified as:

ii) Snowfall: 

• Snowfall is another important form of precipitation. Snow is made up of ice crystals which usually combine to form flakes.
• When these flakes reach the earth’s surface then snowfall occurs. The average density of snow is 0.1 g/cm3.

iii) Drizzle: 

• A fine sprinkle of numerous water droplets which have size less than 0.5 mm and intensity of these water droplets is less than 1 mm/hr, then we call them drizzle.

iv) Glaze: 

• When the water droplet (rain or drizzle) come in contact with ground which have a temperature near about 0° C or less than it, these water drops freeze and form ice coating on ground surface which is called glaze or freezing rain.

v) Sleet: 

• It is frozen raindrops which have transparent grains. These are formed when rainfall is at subfreezing temperature.
• Sleet denotes both rain and snow and the size of sleet is less than 5 mm.

vi) Hail: 

• It is a large size of snow which have size greater than 8 mm. They are in the form of irrigator pellets or lumps of ice.
