Study Notes
Climate of India
- Thar Desert experiences significant temperature fluctuations within a day, while Andaman and Nicobar Islands have minimal temperature variation.
- India experiences diverse precipitation patterns, ranging from snowfall in the Himalayas to heavy rainfall in Meghalaya.
- Annual precipitation varies from over 400 cm in Meghalaya to less than 10 cm in Ladakh and western Rajasthan.
- Most parts of India receive rainfall from June to September, except Tamil Nadu coast which receives a large portion of its rain during October and November.
- Ocean currents and onshore winds influence the climate of coastal areas, causing warming or cooling depending on the current.
Seasons in India
- The monsoon climate is characterized by distinct seasonal patterns with significant weather changes.
- Four main seasons: Cold weather season (Winter), Hot weather season (Summer), Advancing Monsoon (Rainy Season), and Retreating Monsoon.
Cold Weather Season (Winter)
- Beginning in mid-November and lasting till February.
- December and January are the coldest months.
- Temperatures decrease from south to north.
- Average temperature in Chennai: 24°– 25° Celsius.
- Average temperature in northern plains: 10°C to 15° Celsius.
- Days are warm and nights are cold.
- Winter rainfall, known as 'mahawat', is crucial for 'rabi' crops.
- The peninsular region does not have a well-defined cold season.
Hot Weather Season (Summer)
- From March to May.
- Due to the northward movement of the Sun, the global heat belt shifts northwards.
- Temperatures rise significantly, reaching fatal levels in some areas.
- Dust storms are common in May, bringing temporary relief with light rain and cool breeze.
- Local thunderstorms with violent winds and torrential downpours occur.
- Pre-monsoon showers are common in Kerala and Karnataka, known as 'mango showers'.
Advancing Monsoon (The Rainy Season)
- Begins in early June.
- Low-pressure conditions over the northern plains intensify, attracting trade winds from the southern hemisphere.
- South-east trade winds originate over the warm subtropical areas of the southern oceans.
- Monsoon rains are intermittent, occurring for a few days at a time with rainless intervals.
- Breaks in the monsoon are related to the movement of the monsoon trough, which determines the spatial distribution of rainfall.
- Heavy rains can lead to devastating floods in the plains.
- Frequency and intensity of tropical depressions influence the amount and duration of monsoon rains.
Retreating Monsoon
- Low-pressure conditions over north-western India shift to the Bay of Bengal by early November.
- Cyclonic depressions originate over the Andaman Sea and cross the eastern coasts of India, causing heavy and widespread rain.
- Parts of Rajasthan, Gujarat, and the leeward side of the Western Ghats are drought-prone.
Regional Variation in India's Climate
- India's climate varies significantly across different regions due to factors like latitude, altitude, and proximity to the sea.
- Areas with higher altitude experience lower temperatures.
- Coastal regions generally have more moderate temperatures due to the moderating influence of the sea.
- These variations influence the distribution of flora and fauna, agricultural practices, and human settlements.
