Case Study 1: The Monsoon, unlike the trades, does not have steady winds but is pulsating in nature, affected by different atmospheric conditions encountered by it, on its way over the warm tropical seas. The duration of the monsoon is between 100-120 days from early June to mid-September. Around the time of its arrival, the normal rainfall increases suddenly and continues constantly for several days. This is known as the ‘burst’ of the monsoon and can be distinguished from the pre-monsoon showers. The monsoon arrives at the southern tip of the Indian peninsula generally by the first week of June. Subsequently, it proceeds into two-the Arabian Sea branches and the Bay of Bengal branch. The Arabian Sea branch reaches Mumbai about ten days later on approximately the 10th of June. This is a fairly rapid advance. The Bay of Bengal branch also advances rapidly and arrives in Assam in the first week of June. The lofty mountains cause the monsoon winds to deflect towards the west over the Ganga plains. By mid-June, the Arabian Sea branch of the monsoon arrives over Saurashtra-Kuchchh and the central part of the country. The Arabian Sea and the Bay of Bengal branches of the monsoon merge over the northwestern part of the Ganga plains. Delhi generally receives the monsoon showers from the Bay of Bengal branch by the end of June (the tentative date is the 29th of June). By the first week of July, western Uttar Pradesh, Punjab, Haryana, and eastern Rajasthan experience the monsoon. By mid-July, the monsoon reaches Himachal Pradesh and the rest of the country.

Case Study 2: The climate of a region is determined by various factors such as latitude, altitude, distance from the sea, and the presence of mountain ranges. India has a diverse climate due to its vast geographical extent and these influencing factors. The major climatic regions in India include the tropical monsoon, tropical savanna, humid subtropical, hot desert, and alpine climates. The tropical monsoon climate dominates most of India, characterized by distinct wet and dry seasons. The southwest monsoon, which brings rainfall to the country, is a significant feature of this climate. The Himalayan region experiences an alpine climate with cold winters and cool summers. The Thar Desert in Rajasthan represents the hot desert climate, with extremely high temperatures and low rainfall. Understanding the different climatic regions is crucial for agriculture, planning, and adapting to the local environment.
