The primary part of the area of India ( *show more) is in the sub equatorial region. The main feature of this area is tropical monsoons. Summer monsoon coming from the Indian Ocean brings rains to India. They intensify at the begining of June on the western coastline and in mid-June on the eastern coastline. If moving over the Arabian Sea and the Bay of Bengal, the monsoons are saturating with moisture and move around in a northwest way.
Rising over a Western Ghats and Assam Mountains, monsoons go at a speed of 5-7 m/s, causing heavy rainfall. Thunder or wind storms fall on the slopes of the hills in June. Yet later they calm down, and during the time from late September to mid-October rain falls usually, stop. From November to March, the dry northeastern monsoon blows through the land side. It makes the climate cold and sun-drenched.
According to data on thermal conditions, precipitation, and winds, we can separate the calendar year in to three major weather seasons.
In November – February, once the northeastern monsoon dominates, it is cold and sunshiny. In March, the temperature slowly rises.The dry season can last from the end of March to June. At the end of June, the humidity rises. And also the climate of Indian plains gets rainy.The time from July to mid-September is the summer monsoon time. This is a moment of wet tropical weather. The south-westerly winds combine with high temperatures.October is a transitional period. The air humidity is high because of evaporation from the surface of the fields. But the rains end.
There are differences in temperature and also weather in several areas of India. The nation covers a huge location, and every region has yet another terrain. Therefore, in the Thardesert, the annual precipitation does not exceed 100 mm. And at Cherapun jistation in the Khashi Mountains, it is up to 10 770 mm of rainfall each year. It is among the wettest areas on Earth.
The monsoon climate is attribute of the coast of the Arabian Sea. The coldest period of time is from December to February. At the same time, there is fewer rain. The hottest time is from May to June. But even great heat are tolerated very easily since the air is dry, relative humidity, in the morning, does not exceed 60%. Winds boost clouds of dust and change the horizon a dirty yellow.
The start the monsoon in June begins with the increased wind and cloud cover. The period can last until September. Throughout most days of the month, it rains often and lightly. The month to month rainfall in the wettest month – July is much greater than 600 mm. Cloudy weather decreases the temperature by 3-5 degrees.
In the hills of the Himalayas, the climate will depend on the height above sea level. Soat altitudes from 1500 to 2300 meters, from December to February, the average minimal temperature is from 0 to -3C (25 to 32F), and the average maximum heat is +4 to +8C (40 to 45F).
The hottest period of the year lasts from June to August: the standard minimum temperatureis +14 to +18C (55 to 65F), the average maximum temperatureis +29 to +30C (84 to 86F). The summer monsoon does not appear here. The smallest amount of rainfall is from September to November (25-35 mm per month), the highest in March (about 100 mm). As you will see, the climate of India varies greatly depending on the region, its distance from the Ocean, and its altitude. We can not compare Himalayan weather to other portions of India. These mountain tops are very high and have a unique weather.
