2. Types of Precipitation
• The type of precipitation
that falls to the ground
depends upon the
formation process and the
temperatures of the
environment between the
cloud and the surface
4. Rain
• Rain develops when
growing cloud droplets
become too heavy to
remain in the cloud and
as a result, fall toward
the surface as rain
5. • Rain can
also begin as
ice crystals
that collect
each other to
form large
snowflakes
• As the falling
snow passes
through the
freezing level
into warmer
air, the
flakes melt
11. Hail
• Hail can vary
in size, from
the size of a
small stone to
that of a
baseball! So
be careful
12. Sleet
• Sleet is frozen raindrops.
Sleet begins as rain or
snow and falls through a
deep layer of cold air that
contains temperatures
below freezing that exist
near the surface.
13. Sleet
• Rain that falls
through this
extremely cold
layer has time
to freeze into
small pieces of
ice
14. Freezing Rain
• Freezing rain is falling rain
that cools below 0°C, but
does not turn to ice in the
air
• The water is “supercooled”
22. 4. Air cools as it is
forced to rise
5. Condensation
6. Clouds form
7. Rain
23. Convectional rain is
common in the
Rajasthan and Plain
areas of India in
Summer
It is also common in
Equatorial region of
the world along
equatorial low
pressure belt rgion
everyday between 2
25. 3. Frontal Rain or Cyclonic
1. Mass of warm air meets
a mass of colder air
2. Lighter warm air
rises over heavier
cold air in the
temperate region
along Warm and
Cold front
26. 3. Warm air cools
4. Condensation
5. Clouds form
6. Rain
27. Frontal rain is very common all Temperate
regions of the world
