| Abstract | Climate change has become a major concern in every field without exception to fresh-water resources. This study performs the trend analysis of meteorological variables in the Balu Chaung Basin, Myanmar. Balu Chaung Basin is the home of Inle Lake which is a lake with great significance to not only Myanmar but the international community too. For the analysis temperature and rainfall variables were used as meteorological variables. Daily data of 5 stations of different time periods were taken for trend analysis. The analysis was done by using exploratory methods- time series plot.
As the first sub objective of the study, time series plot was used to describe the trends of the selected 12 climate indices (4 temperature: TXx, TNx, TXn and TNn; 8 precipitation: R10, R20, R5, CDD, CWD, R95p, R99p, PRCPTOT) in all the stations and the slope and probability value were compared. For the second part, the averages of the climate indices in three periods (1980-1990, 1995-1999, 2001-2005) were compared with the respective overall average of respective stations to find the variations in climate change.
Although when looked upon individually, the stations have some variations in the level of change with each other but when the basin as a whole is taken into account, the results of the study show that there has been a general increase in all temperature indices in the basin and a general decrease in total precipitation amount in the basin, though the level of precipitation has varied. The stations could not be grouped according to elevation or location because of inconsistent trends.
While the results show that station Pinlaung that lies in the central part along the basin has witnessed relatively more number of consecutive dry days and days with rainfall above 5mm, 10mm and 20mm, station Loikaw at the end of the basin was found to be hotter than other stations throughout the overall period and in the specifically considered three periods. During the three periods, when the overall increase or decrease in climate indices of all stations were looked at, overall the temperature indices were increasing and precipitation indices were decreasing. The consecutive dry days and wet days have some variations within the stations but it can be seen that the wet days are decreasing while dry days are increasing. |
