Southern Asian Monsoons: A Meteorological Study

Why does South Asian monsoon have an important monsoon every year in many countries around the world? Certainly Indian monsoon is the biggest phenomenon, there is no reason to disable other phenomena. What is the meaning of the monsoon for the people living in the disaster area? In India, people's lives are balanced at the cutting edge. At the 2009 census, over 40% of the total population (over 1 billion and over 1.5 billion) were below the international poverty line of $ 25 a day.

In 1686, Edmund Halley published a paper on Indian summer monsoon. This is because the land in Asia and heating in the Indian Ocean are different, we believe that the monsoon has been reversed. The first meteorological observatory was founded in India by the British East India Company. These include the Kolkata Observatory in 1785, the Madras Observatory in 1796, and the Colaba Observatory in 1826. In the first half of the 19th century, the provincial government established several other observatory stations in India.

The Indian Meteorological Department (IMD) said Tuesday, the monsoon moved further to the South Arabian Sea and the Southwest Bengal Bay, and is expected to attack South Kerala by June. Formerly IMD set the arrival date of monsoon as Kerala as June 7, give and take 4 days. The IMD meteorologist says that Kerala's monsoon will start on June 9 in terms of strengthening the flow across the equator and accelerating the westerly wind on the South Arabian sea. There may be a slight delay in central India, but further progress will be normal

Kerala in India received the highest precipitation in India during the monsoon. However, during the year 2018, the state experienced the highest monsoon rainfall for decades. According to the Indian Meteorological Department (IMD), the precipitation is 2346.3 mm rather than the average 1649.55 mm. Unprecedented rainfall is caused by regional low pressure. The southwest monsoon system is fully integrated with the two low pressure systems formed in Bengal Bay and Orissa. A region of low pressure pulls the moist southwest monsoon and speeds up, then it crashes into the western Ghats mountain range and fly to the sky to form a rain cloud
