The subtropical humid climate region refers to the northeast region of the country where summer temperature lies between 35-40 degrees centigrade and winter temperature lies between 2-4 degrees centigrade. The average difference in the day and night temperature varies due to the evaporation of the water from the atmosphere. The rainfall occurs mainly in the summer and occasionally occurs in the winter also. The average rainfall in the humid and hot northeast part lies below 1000 -1500 mm. The hottest period in the northeast humid region is the month of May and June.
What is a humid climate?
Humid climate refers to the wet climate region in the country. Most of the northeast region of the country comes under the humid and hot climate zone where little precipitation occurs during the winter. Based on the monsoon rain India has two subtropical climate zones and based on the zone the downward flow of wind occurs from the central part of Asia. The humid subtropical regions are defined as the dry winter period where the average moisture content of the atmosphere falls. However, the precipitation value is low in the winter therefore there is a chance of snowfall in the winter period in the subtropical humid climate.
Explain the humid climate area of India
Most summer rainfall occurs in the northeast part in the mid of May-June with the powerful thunderstorms associated with the poorer monsoon rainfall. The occasional tropical cyclones are also associated with thunderstorms and rainfalls in the northeast region of the country. The average annual rainfall in the west is 1000 mm and in the far north, east is 2000 mm. Moreover, most of the northeast region is far away from the sea, therefore the continental climate predominates in the region. India’s Northeast part is mainly constructed with the mountains and has an adiabatic rate of 9.8 degrees centigrade per km.
Why is the climate near the sea humid?
The climate near the sea is humid as the water is evaporated by the radiation of the sun and absorbed by the atmosphere. The absorbed moisture in the atmosphere increases the moisture content, therefore the temperature becomes hybrid. Air near the coast of the sea line holds high moisture and temperature and due to this, the climate becomes humid in the region. Earth’s surface in the sea region traps heat from the sea surfaces due to the heating of the water and increases the humidity in the atmosphere. The air in the sea area transfers from the high-density zone to the low-density zone, therefore the air moves from the high-density region to the coastal region.
What is a hot and humid climate?
Hot and humid climate refers to the tropical and sea coast region climate where a maximum amount of water is absorbed by the atmosphere. The hot climate zone is the dry climate zone of northeast India where average rainfall falls below 1000 mm on a yearly basis. The semi-arid region also comes under the hot climate zones. The tropical hot and dry climate generally evaporates the water from the atmosphere and due to this moisture content becomes very low. The humid climate zone refers to the sea area and Ganges belt, a tropical wet region where average rainfall falls between 1500-2000mm.
Describe the hot and humid climate region in Northeast India
The region of Northeast India like Arunachal Pradesh has a hot and humid climate due to the lower altitude. Moreover, the high altitude of the forest region has relatively dry weather due to the evaporation of water from the earth’s atmosphere. The average temperature in the region falls between 15- 20 degrees centigrade in the winter months. However, in the high altitude area, the average temperature falls below the chilling temperature.
What is the impact of the hot and humid climate in the North East?
The hot and humid climate in the northeast changes the precipitation level in the earth’s atmosphere and impacts the sea level rise. The increased temperature in the dry area affects the green environment and reduces the sustainability of the biodiversity in the region. The northeast Indian climate is the driver of the subtropical climate and maintains the average rainfall in the mountain region or tropical wet region.
Conclusion
The above study indicates that the hot and humid region of the northeast has an average rainfall of 1000 mm yearly. The rainfall in Arunachal Pradesh is among the heaviest rainfall in the region that is more than the annual rainfall of 350 cm. The blowing of the air from the high-density zone to the low-density zone brings lots of vapour that increases the humidity of the sea area.
