dc.description.abstractA new interpretation of the start of summer monsoon along central west coast of India is presented in this paper. Many authors misinterpret onset of continuous rains as start of summer monsoon front, These two are different phenomena, continuous rains happening during the last phase of monsoon development as a consequence of and after (2-5 weeks) the establishment of monsoon circulation or monsoon front. Summer monsoon front, as the term 'monsoon' originally meant, is to be delineated from the patterns of winds at surface and upto about 2 km height (observable from cloud movements) and becomes established during the first week (approximately) of May at Panjim (15 degrees 29 minutes N and 73 degrees 49 minutes E), a coastal station, which can be considered representative for a long coastal belt, west of Western Ghats, called here the central west coast of India. Before the establishment of summer monsoon front at Panjim, establishment of thermal front, humidity front and cloud front happen indicating start of hot and humid summer by about mid-April. Intensification of Indo-Pak Low and easterly upper tropospheric jet happen during May-June only (onset period for rain front also), two prerequisites for continuous rains. Day to day variations of surface temperatures, surface winds, humidities, clouds, upper winds and rainfalls are studied for the years 2000 and 1995 (year of earliest onset in a century and a delayed onset, respectively) to bring out patterns of change during progression of seasons. Similar situations can exist in other regions of the Asian Summer Monsoon sector with some differences
