摘要

Data collection and analysis of meteorological parameters has been further updated and carried out for all the seven locations in East India, on yearly, weekly and daily basis. The data in Figure 1 represent South bank region of Assam and the 96 yearsof data which although continues to shows an overall decline of nearly 200 mm but it also shows that when compared to previous years rainfall (2014) the year 2015 has shown a rise in total rainfall of around 280 mm with respect to 2014. A closer look atthe data of these two years (2014 and 2015) when analysed in weekly basis gives an answer to the rise in total rainfall in the year 2015. The data presented in Figure 2 represent the weekly data of the South bank region of Assam for the year 2014 and 2015. The figure shows that in the year 2014 there was almost no rain after the month of June whereas in 2015 rainfall continued till end of October. Such trends of high and low rainfall variability from year to year basis bring about too much (flood) andtoo less (drought) water availability in tea gardens.
