In this article, we will discuss Climatic Divisions by Stamp and Kendrew (Sub-tropical Climate). So, let’s get started.
Climatic Divisions By Stamp and Kendrew (Sub-tropical Climate)
Sub-tropical climate of India
The Subtropical climate has been subdivided into:
1. The Himalayan Region
Stretching over the mountainous parts of Jammu and Kashmir, Ladakh, Himachal Pradesh, Uttarakhand, Sikkim and Arunachal Pradesh, it has mild summers and cold winters. The regional distribution of temperature is largely controlled by the topography and aspect of slope. Upto a height of 2500 metres, the average temperature of winter season ranges from 4°C to 8°C, and the summer temperature varies from 12°C to 18°C. Rainfall is recorded from the South-West Monsoon in summer and from the western disturbances in the winter season. The amount of rainfall decreases from east to west. For example, in eastern Uttarakhand the average annual rainfall is over 200 cm, while in western parts of Jammu and Kashmir it falls below 150 cm. Snowfall and sleet are the common features in the Greater and Lesser Himalayas during the winter months (December to March)
2. The North-Western Region
This type of climate is found to the north-west of Satluj river where the average temperature of the winter season reads around 15°C. The mean minimum temperature in the month of January may occasionally fall below the freezing point at Amritsar. The mean maximum temperature in the month of May and June may cross 45°C. Hot winds (Loo) and dust storms during the scorching summer are the other features of this climatic region.
3. The Dry Plains of North-West India
This climate stretches over Rajasthan, Kutch, and south-western parts of Haryana. In this region the winter temperature ranges between 15°C and 25°C, but occasionally, the maximum temperature crosses 47°C in the month of May and June. The average annual rainfall is below 25cm and occurs mainly during the month of July and August; the season of general rainfall.
4. Areas of Moderate Rainfall
This climatic division stretches over Punjab, Haryana, the Union Territory of Delhi, western Uttar Pradesh, eastern Rajasthan, and western Madhya Pradesh. The average rainfall in this climatic division varies between 40 to 100 cm. The mean temperature of January varies between 15°C to 18°C Over 85% of the total rainfall is recorded during the season of general rains. Delhi, Ludhiana and Meerut are typical example of this climate. This climate is found in eastern Uttar Pradesh, western and North-western Bihar, and north-western Jharkhand. The average annual rainfall in this zone varies between 100 to 150cm. Over 90% of the total annual rainfall is recorded during the season of general rains from the Bay of Bengal stream of the South-West Monsoon. The mean January temperature reads about 15°C while the mean maximum in the month of July reads over 40°C.
