[AAS05-11] PRECIPITATION EXTREAME
キーワード：Precipitation, Temperature, Humidity
Precipitation extreme is one of the major evidence among all the natural calamities as
a result of climate change. The global precipitation has increased at an average rate of 0.08 inch
per decades which indicate a major threat to the future decades. There are several causes
observed for extreme precipitation event over the last century, the rising of global temperature
which is the main culprit for increasing evaporation rate that leads a significant role in extreme
precipitation event. Other’s factors such as decreasing humidity and increasing wind speed that’s
also plays important role in promoting evaporation rate. Finally it can be say that the more heat,
more moisture causes more evaporation which leads to more precipitation event The
consequences of extreme precipitation event are already known to all. It may occur frequent
flood in deferent region over the world. A recent study has shown that approximately 82000
people’s affected and 26000 km² is flooded per year in Bangladesh due to monsoon flood. The
extreme precipitation event creates negative impact on economic, agriculture and environment
regions and also directly impact on storm water management and public health. The weather
forecasting will contribute to reduce the agriculture, economic, environmental impact by
predicting the extreme precipitation event occurrence time of future decades. It will also help to
take necessary steps against future natural clematises. In this study a complete data analysis of
daily and sub-daily precipitation, temperature and humidity of different rain gauge station in
Bangladesh from 1961 to 2014 has done to determine the maximum extreme region. By using
MATLAB TSAF toolbox, A time series analysis and forecasting of daily and sub-daily
precipitation has done. This analysis will contribute to the global community to determine the
present condition of precipitation rate of Bangladesh and will help to take global precautionary
measures against the future precipitation extreme.
