What are the characteristics of Indian monsoon rains? And what are the conditions?
India's monsoons are of greatest concern to agriculture, economy and the livelihood of billions of people in the country.
South Asia. However, little attention has been paid to the possibility of distinct subseasonal episodes in the locked phase
The annual cycle of the Indian monsoon. This study objectively addresses this gap by using the self-organizing map (SOM) method
Six distinct sub-seasonal phases are classified based on 850 hPa wind fields. Each sub-seasonal stage is between 23 and 90 days.
The Indian summer monsoon (ISM) consists of three subphases: ISM onset, ISM peak, and overall ISM exit.
It accounts for 82% of the annual rainfall. The three sub-stages represent rapid progress to the north, dominance and
Gradual retreat of southwesterlies from mid-May to early October. The winter monsoon also includes three
sub-phases (autumn, winter and spring), recognizable by the latitude of the Arabian Sea high pressure ridge and hydrological
The conditions of this study suggest two compact indices based on regional winds in the north and south of the Arabian Sea.
Measure the winter and summer monsoons respectively. These indicators show development and rotation
Six stages are derived from SOM and can be used to monitor and predict sub-seasonal monsoons. Spring and the start of the ISM
Episodes are highly susceptible to the combined risks of drought and heat wave, while the greatest flood risk occurs during
The peak phase of the ISM, the autumn phase, reflects the peak season of tropical cyclones over the Arabian Sea and the Bay of Bengal.
There are four seasonal divisions in India, out of which two are monsoon divisions. This automatically makes us aware of the importance of the Indian Monsoon. Also, India is an agricultural country and the onset of monsoon in India majorly contributes to the GDP of the country. A good monsoon brings economic prosperity for the whole country and boosts the Indian economy as agriculture contributes around 16 per cent of its total Gross domestic product GDP. High temperature and heavy rainfall in the summer months are important for different types of kharif crops
Based on the time of year that these winds bring rain to India, the monsoon can also be categorized into two periods:
1. Summer monsoon (May to September)
2. Winter monsoon (October to November)
Indian monsoon, the most prominent of the world’s monsoon systems, which primarily affects India and its surrounding water bodies. It blows from the northeast. At the Equator the area near India is unique in that dominant or frequent westerly winds occur at the surface almost constantly throughout the year;
Features of Indian monsoon:
Dry spell and wet spell: Monsoon in India has clearly marked wet phase and dry phase, characterized by weeks where there is no rainfall.
Unequal distribution: Monsoon rains are unequally distributed with peninsular part of India receiving more rainfall than the plains.
Topographic influence: Monsoons are influenced by topography. The Western side of the Western Ghats receives heavy rainfall whereas the eastern side is deficient.
Fixed schedule: Monsoons in India have typically a fixed schedule. It usually begins by June first week and ends by September.... Read more at: https://www.studyiq.com/articles/characteristics-of-indian-monsoon/
