Spatio–Temporal Variation of Precipitation in Kashmir Valley, Global Teleconnections

Wani Rashid Ashraf

Abstract :

The impacts of climate variability and change are global concerns. This study analyses the frequency of local and teleconnective association between precipitations over Kashmir valley and NAO using the monthly data for the period 1975-2009. Regression and correlation methods are used to analyze the spatial variation in precipitation. The overall association of the stations is analyzed by fitting a linear least square trend line to the annual deviation from the mean. All the stations except Qazigund have shown a decreasing trend. Correlation analyses have been discovered using Karl Pearson’s method. A significant positive correlation is found at stations of Srinagar, Kupwara and Qazigund. The correlation of the stations during spring and summer seasons is also showing high degree of positive correlation. Most of the stations are strongly correlated with each other. Also the investigation of the association of NAO and precipitation shows a positive correlation in winter for most of the stations. However least positive correlation was found in summer.
