Example: Monsoon, equatorial desert, cold climate etc.
We can take two important elements, Temperature
and Precipitation, and examine how they vary from
place to place and season to season.
Temperature variations:
Rajasthan desert: up to 50°C in summer
Pahalgam, Jammu and Kashmir: around 20°C in
summer
India has Diverse Climatic
Conditions

Meghalaya, less than 10 cm in Ladakh and
western Rajasthan
Rainy season: June to September for most
parts, October and November for the Tamil
