Heat budget, also known as the energy budget or radiation budget, refers to the balance of incoming and outgoing energy flows in Earth’s atmosphere and surface. This balance is crucial for understanding and predicting climate patterns and changes.
Incoming solar radiation, or insolation, is the primary source of energy for Earth’s heat budget. This energy is largely absorbed by the Earth’s surface, heating it and driving atmospheric circulation and ocean currents. Some of the incoming solar radiation is also reflected into space by clouds, aerosols, and the Earth’s surface itself.
Once absorbed, the Earth re-emits this energy as longwave infrared radiation. Greenhouse gases, such as carbon dioxide and water vapor, trap some of this outgoing radiation in the atmosphere, thereby warming the planet in a natural process known as the greenhouse effect.
In Earth’s heat budget, approximately 70% of incoming solar radiation is absorbed by the atmosphere, land, and oceans, while 30% is reflected in space. For outgoing waves, about 70% of heat is radiated back into space, and 30% is absorbed by the atmosphere and clouds.
The heat budget varies across different regions and seasons due to factors like latitude, altitude, cloud cover, and surface characteristics (such as land or ocean). Imbalances in the heat budget can lead to changes in temperature, precipitation patterns, and weather events, influencing regional climates and global climate trends over time.

India’s economy is highly dependent in agriculture contributing about 14% of the total GDP of the state. Thus most of the people in India are heavily dependent upon agriculture. The monsoon pattern is to thank for as the favorable moisture laden winds help in the abundance of agricultural activity in the state.
Starting from the month of June the south east monsoon winds of the Arabian sea branch hits the cost of Kerela due to the formation of low pressure region of the Indian subcontinent and the shifting of the ITCZ towards the tropic of cancer. Heavy showers are received in the Western ghat region after which the winds travels over the semi arid Indian peninsula moving northwards and being obstructed by the Great Himalayas. This causes showers over the Indo Gangatic plains where maximum of the wheat production is done in the states of Punjab, Haryana and Uttar Pradesh and most of the northern belts.
The Bay of Bengal branch of the south east monsoon winds brings heavy showers to the eastern and north eastern states of India where rice production id very prevalent. Mawsynram in the north eastern state of Meghalaya is the rainiest place in the world with an annual rainfall of 467.4 in annually.
Other arid and the semi arid regions like the north western and the Deccan region grow cash crops like cotton, rubber, sugarcane etc. The amount of rainfall received during the monsoon in the particular state determines the climatic zone of the state and the dominant crop of the state.
The uneven distribution of rainfall in India makes it a diverse agricultural boul.
