Abstract:
India’s dependence on monsoon rains is quite high. India has a predominantly agricultural economy. More significantly, over 60% of the population including several million small farming households, is dependent on agriculture as their primary source of income and land continues to be their main source of economic stability. Therefore, it is acceptable to say that India's monsoon does play a significant role. Rainfall activities varied between subregion at the time of onset. Rainfall actions during withdrawal can also be classified as sudden, slow, or weak. Hence, the current study, “Determination of onset and withdrawal of monsoon for different tehsils in Jalgaon district in Maharashtra”. The long term, daily rainfall data of 61years (1961-2021) were used to compute annual and monthly rainfall of fifteen tehsils of Jalgaon district. The onset and withdrawal of the rainy season were calculated using forward and backward accumulation method from mean weekly rainfall data. According to the assessment of weekly rainfall data, the mean week of the onset of monsoon has found to be 26 standard meteorological week for all of the tehsils in the Jalgaon district, except Muktainagar tehsil, where the mean onset was 27 standard meteorological week.
