This time, the country is expected to receive more than normal rainfall in the monsoon season (June to September). The Meteorological Department said that it could be 106%. Last month it was reported to be 105%. At the same time, rainfall will be more than normal in the month of June as well. The Meteorological Department (IMD) said on Tuesday, ‘The country is expected to receive more than normal rainfall in the month of June, which could be 108%. That is, more than 87 cm of rain is expected during this period. This is called Long Period Average i.e. LPA. More rain expected in MP, Maharashtra, less rain in Bihar-Jharkhand What is Long Period Average It means that the Meteorological Department has fixed the Long Period Average (LPA) for the southwest monsoon as 87 cm (870 mm) on the basis of the period 1971-2020. If the rainfall in a year is more than 87 cm, then it is considered more than normal. If it is less, then it is considered a weak monsoon. Know what is Bharat Forecast System The Government of India today launched the Advanced Bharat Forecast System (BFS). Union Minister of State for Science and Technology Dr. Jitendra Singh handed it over to the country. This system will help in disaster management, agriculture, water management and public safety up to the panchayat level. The BFS system will give more accurate and minute information about the weather than ever before. Pune’s Indian Institute of Tropical Metrology (IITM) has prepared it. The BFS system will forecast the weather at a resolution of 6 KM, which is the best in the world. With this, even the smallest weather-related events like rain, storm can be detected more accurately than before. Ministry of Earth Science Secretary M Ravichandran said that now the weather forecast will be more local and accurate than before. He said that earlier the supercomputer Pratyush was being used, but now the new supercomputer Arka will be used. Pratyush used to take 10 hours to run the weather model, while Arka completes the work in just 4 hours. This system takes data from 40 Doppler radars and will be further improved with 100 radars in future. This will make 2-hour local forecasts possible. Monsoon reached Kerala 8 days before the scheduled time The southwest monsoon reached Kerala on May 24, 8 days before the scheduled time. This happened after 16 years. It reached Kerala on May 23 in 2009. The system that brings rain to Mumbai became active 16 days earlier. This is the earliest since 1950. Usually the southwest monsoon reaches Kerala by June 1. It reaches Mumbai by June 11 and spreads across the country by July 8. Its return from northwest India begins on September 17 and it completely returns by October 15. The main reason for the early arrival of monsoon in India this time is the increased humidity in the Arabian Sea and the Bay of Bengal. The sea temperature was higher than normal, due to which monsoon winds became active rapidly. The movement of western winds and cyclones also helped the monsoon to move forward. Apart from this, climate change is also becoming a major reason for change in weather pattern.
