Climate by Mind Map: Climate

1. Factors Affecting Indian's Climate

1.1. Altitude

1.1.1. As the Tropic of Cancer passes through the middle of the country, India experiences both tropical and sub-tropical climate.

1.2. Altitude

1.2.1. The temperature and density of air decreases with the increase in altitude and vice-versa

1.3. Pressure and winds

1.3.1. The movement and direction of winds influence India's climate which experiences heavy rainfall due to the movement of high-pressure winds to the low-pressure belt over the Indian subcontinent.

1.4. Distance from the sea

1.4.1. As the distance from the sea increases, temperature rises and vice-versa

1.5. Ocean Currents

1.5.1. While warm ocean currents increase the temperature of the areas surrounding the ocean, cold ocean currents have a cooling effect on the coastal areas.

1.6. Relief

2. While the windward side of the mountains experiences rainfall, the leeward side remains dry due to the lack of natural barrier

3. Different Seasons Of India

3.1. The Cold Weather Season (Winters)

3.1.1. From mid November to February Between 24°-25°C in southern India, between 10°-15°C in nothern parts of India

3.1.2. 1. Remains mostly dry 2. Cyclonic disturbances which enter India from the west and the north-east cause rainfall in the northern plains. 3. The rainfall is beneficial for rabi crops

3.2. The Hot Weather

3.2.1. March to May 38-45°C, slightly lower temperatures in coastal areas, cool weather in mountains 1. The low-pressure belt over the Indian subcontinent attracts the south-east trade winds. 2. These winds pick up moisture from the Indian ocean and enter India as the south-west monsoon winds. 3. The period is marked by heavy rainfall in the north-eastern parts as well as the Western Ghats.

3.3. The Rainy Season

3.3.1. June to mid-September 27°-35°C

3.4. The Transition Season (Post-monsoon)

3.4.1. October-November 20°-34°C

3.4.2. 1. This period marks the withdrawal of monsoon winds from the mainland. 2. The low-pressure belt shifts to the Bay of Bengal which leads to the formation of cyclones over the Andaman Sea. 3. These cyclones cause heavy rainfall in the deltas of the Godavari, Krishna and Kaveri rivers.

4. Jet Stream

4.1. A narrow belt of high-altitude westerly winds in the troposphere.

5. Monsoon Winds

5.1. These winds blow over the Indian subcontinent from June to mid-September are bring heavy rainfall across India. They pick up moisture from the Indian Ocean and cause rainfall over the low-pressure belt that forms over India due to high temperature.

6. Weather

6.1. The state of the atmosphere over an areas at any point of time.

7. 1. A low-pressure belt develops over the Indian subcontinent. 2. Hot,dry winds known as "loo" blow over the northern and north western parts of Indian. 3. The torrential rainfall announces the arrival of monsoon.
