Indian Climate and Seasons

Deciduous forests in India are found in the areas where 65-100 cm rainfall occurs.

  In India , area under forests is far below the required percentage because of large population.,large area used for the purpose of cultivation.

West Bengal has the highest concentration of jute mills primarily because the state and its neighboring regions (especially Bangladesh) are the primary jute-growing areas. Proximity to raw materials reduces transportation costs and ensures steady supply. While cheap labor and climate are favorable factors, the raw material availability was the decisive locational factor for jute industry concentration.

South India's tropical climate (higher temperatures, longer sunshine hours, and adequate rainfall in coastal areas) supports higher sucrose content in sugarcane and allows a longer crushing season (8-9 months vs 4-6 months in North). Coastal areas also have better water access. North India faces frost risk and shorter season.

Mountains influence rainfall through orographic effect - when moist air is forced to rise up mountain slopes, it cools and condenses, causing precipitation. Soil type affects water retention but not rainfall formation. Population density and sunrise/sunset times are unrelated to atmospheric processes that create rain.

The Himalayas act as a climatic barrier for northern India by blocking cold winds from central Asia and trapping monsoon moisture. They create rain shadows and prevent extreme temperature variations. Southern India is protected by the Western Ghats and Eastern Ghats, not the Himalayas.

The location of mountains significantly influences rainfall through orographic lifting - when moist air is forced to rise over mountains, it cools and condenses, causing rainfall on the windward side. This creates rain shadows on the leeward side. Type of soil affects vegetation and water retention but not rainfall generation. Population density has no direct relation to rainfall. Sunrise and sunset are daily occurrences, not rainfall factors. Mountain location is a major climatic control.

The Himalayas act as a climatic barrier for the entire Indian subcontinent, but they most directly affect northern India. They block cold Central Asian winds in winter and trap monsoon winds, causing heavy rainfall. Southern India is protected by the Western and Eastern Ghats, while the Himalayas are the primary climate modifier for the northern plains.

The definition of severe drought conditions is based on rainfall deficiency percentages. According to meteorological standards, when annual rainfall deficiency exceeds 50% of normal (long-term average), the region is considered to be experiencing severe drought. Options A and B represent moderate deficiency levels, while option D (70%+) would represent extreme drought.

The condition of absence/deficit of rainfall from the normal is known as meteorological drought.

Sunny environment is required for four weeks.

In the North Indian Ocean Basin, the cyclone season runs from April to December, with peak activity between May and November. Widespread deaths and property destruction are reported every year in exposed coastal states such as Andhra Pradesh, Orissa, Tamil Nadu and West Bengal. India's western coast bordering the more placid Arabian Sea, experiences cyclones only rarely. These mainly strike Gujarat and less frequently Kerala.

The 2009 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. Cyclone Aila was the second tropical cyclone of the 2009 North Indian Ocean cyclone season. A relatively strong tropical cyclone, it caused extensive damage in India and Bangladesh. Cyclone Bijli was the first tropical cyclone to form during the 2009 North Indian Ocean cyclone season.

Something different in the two halves; and this is an unusual feature of this year’s monsoon.

July is compared with all other months. So, it is the wettest.
