The winter rainfall in Nepal is mainly affected by large scale weather disturbances and has completely different dynamically features as compared with the summer season.Most of the previous researches are mainly focused on the summer monsoon rainfall over Nepal and studies on winter monsoon are still limited.Thus, it is important to understand the spatial and temporal variation of winter rainfall over Nepal on a climatological perspective.This paper aims to investigate the characteristic feature of winter rainfall in Nepal from 1980 to 2007 and establish a relationship between ENSO and winter rainfall in Nepal by using ERA-Interim and APHORDITE reanalysis data set.The spatial distribution of DJF rainfall over Nepal shows high rainfall in the western to central Nepal with gradual increase from east to west.The correlation analysis between all Nepal winter rainfall and Nino3.4 shows negative correlation of-0.26, however the relation is not consistent over time.Further,the winter rainfall in Nepal is positively correlated with westerly index with statistically significant correlation coefficient of 0.34.The composite rainfall analysis for different E1Nino (1981, 1988, 1996, 1998, 1999, 2000, and 2007) and La Nina (1982, 1986, 1989, 1991, 1992, 1997, 2002, and 2004) years reveals above (below) normal rainfall during La Nina (El Nino) years.This is possible due to strengthening (weakening) of 550hPa westerly flow during La Nina (El Nino) years.Similarly, the moist air advection is suppressed (enhanced) during E1 Nino (La Nina) years resulting into significant variation on winter rainfall over Nepal.
