The months of March to May are hot and dry with mean monthly temperatures of around 32 °C. He identified five major climatic types, namely: i Tropical climates, where mean monthly temperature throughout the year is over 18°C. These agro-climatic conditions are most suitable for the cultivation of groundnut, cotton and wheat. Coromandel coast experiences this type of climate. The region has the dominance of rice, sugarcane, maize, pulses and millets fodder in the kharif season and that of wheat, oilseeds, pulses gram, lentil , potato and vegetables in the rabi season.
It receives rainfall from the summer monsoons, originating from both the Arabian Sea and the Bay of Bengal. А, В, С and H are found in India. Humid sub-tropical climate group Most of Northern India experiences the Sub-Tropical Humid type of climate. The annual rainfall is 150 cm. The northern boundary of this climatic region roughly coincides with the Tropic of Cancer. The area to the south of the Himalayan range is protected from cold winds coming from interior of Asia during winter.
С: Middle-latitude rainy climate with mild winters. Chennai is the representative city of this region. This climate is a transitional climate falling between tropical desert and humid sub-tropical, with temperatures which are less extreme than the desert climate. In the Himalayas where the southern slopes are protected from cold, northerly winds accessible to the south-west monsoons, there is heavy rainfall on the slopes which are at a height of 1,069-2,286 m above sea level. The average temperature is above 27°C but the rainfall is below 100 cm.
The vegetation mostly comprises short coarse grass. Hot desert type Bwhw 6. This extreme climate makes this a sparsely populated region of India. The summer months of May and June are very hot with mean monthly temperatures in the region of 35 °C and highs which can sometimes reach 50 °C. The average annual rainfall is 100-200 cm. Dense forests and plantation agriculture with crops like tea, coffee and spices are the characteristic vegetation in the area.
It is on this basis that the climatic regions can be identified. The Temperate or Continental India has been divided into following five regions: 1. Maximum temperatures during summer can rise to 45 °C. Trewartha and Johnson are worth mentioning. Climatic Regions Tropical Rainy Climate Group The regions that fall under this climatic group normally experience extremely high temperatures.
January temperature is 9° to 24°C which rises to 24°-41°C in July. Climate Related Calamities Climate related calamities are a great cause of loss to the life and property. Regions in the Plains: The plains are interposed between the Himalayas and the peninsular plateau and consist of the following regions: 6. The Trans-Himalayan belt situated to the northern side of the western Himalayas has a climate which is dry and cold. Temperatures remain around 18°C in January and rise to 32°- 35°C in July. Hence this area is not very well suited for permanent agriculture.
Region of moderate rainfall: It includes mostly those areas between Western and Eastern Ghats which receive annual rainfall of 50-100 cm. It is found in Jammu and Kashmir, Himachal Pradesh, Punjab, and Uttaranchal in the west and Arunachal Pradesh, Sikkim and parts of upper Assam in the east. The rainy season is from June to September and the annual rainfall is between 75 and 150 cm. The rainfall is received mostly in the summer and is about 65 cm in the west and increases to 250 cm annually to the east and near the Himalayas. It is characterised by high temperatures throughout the year, even in the hills. Hot Desert Region: It is found in the desert region of western Rajasthan. The western disturbances originate over the Mediterranean Sea and influence the weather conditions in the Western Himalayan region.
Erratic, excess or untimely monsoon rains can kill thousands of people and also harm the agriculture of the country. Of these only 12 climatic types are found in India. Dry climate group This group consists of regions where the rate of of water is higher than the rate of received through. Tropical wet and dry climate or the savannah climate is most common in the country and prevails mainly in the inland peninsular region of the country except for some portion of the Western Ghats. Four major climatic groups A, B, C, and H which are further subdivided into seven climatic types have been recognised. It is characterised by high temperatures throughout the year, even in the hills. Koeppen identified five major climatic types— tropical climates, dry climates, warm climates, snow climates and ice- climates.
A striking feature of this region is a gradual increase in rainfall eastwards, reflected also in the nature of vegetation and soils. The low temperatures, snowing and inclement weather in winters hinder the intensification of agriculture. This area receives minimal rainfall due to being situated in the rainshadow area. Thus, these islands receive abundant rainfall and have hardly any winter season. There is little seasonal variation in climate. The Gangetic Plains are of uniform relief formed by heavy deposition work carried out by the Ganga and its tributaries. Tobacco is an important cash crop in the coastal Andhra Pradesh.
Tropical, Semi-arid and Sub-tropical Steppe Region: This climate is found in the rain-shadow region of the Western Ghats, eastern Rajasthan, and south-eastern Punjab. Temperatures are very high in summer. Barley, wheat, oats, peas sown in October in some areas show a stunted growth during the winters when temperatures are generally below the freezing point. Subhumid Transition: It embraces the eastern part of Uttar Pradesh, Bihar and northern part of Jharkhand. Sub-tropical humid wet with dry winters The foothills of the Himalayas, Punjab-Haryana plain adjacent to the Himalayas, east of the range, , and northern part of and Assam experience this climate.
