Increasing influence of ENSO and decreasing influence of AO/NAO in the recent decades over northwest India winter precipitation

Abstract: [1] The interannual variability of northwest India winter precipitation (NWIWP) is examined in association with the variability of surface temperature, mean sea level pressure, tropospheric geopotential height, and wind patterns over the globe to study the changes in the large-scale circulation features associated with NWIWP. The data for the study have been considered from 1950 to 2008 (for a period of 59 years). The analysis is based on correlations and composites performed using India Meteorological Departm… Show more

“…The location and intensity of the jet strongly influences large-scale dynamical processes in mid-latitudes (Vallis and Gerber 2008), and serves as a wave-guide, bridging atmospheric variability upstream of High Mountain Asia to regional climate (Zhu et al 2011). The strengthening of U200 over the Himalaya is associated with enhanced WWD activity (Yadav et al 2009). Figure 13(right column) displays APH-RODITE derived mean monthly precipitation composites for 85th percentile (positive) index minus 15th percentile (negative) for the period 1979-2007.…”

“…It has a direct influence on the interannual variability of the westerly winds (westerly disturbances) and their water content traversing Europe, the Mediterranean and the Middle East region into the mountains of the UIB (Yadav et al, 2009a;Syed et al, 2010;Filippi et al, 2014). Indices of the NAO have been related to: UIB station winter precipitation (Archer and Fowler, 2004;Afzal et al, 2013;Filippi et al, 2014); western Indus basin's winter snow cover and station precipitation 20 (Hasson et al, 2014); Pakistan station temperature (del Río et al, 2013); and winter precipitation in northwest India (Kar and Rana, 2014).…”

“…In the northern and northwestern parts of India, the winters during El Niño events tend to be wet and cold, and La Niña winters tend to be warm and dry (Yadav et al 2009(Yadav et al , 2010Kar and Rana 2013). The wintertime temperature variability over this region has been relatively less explored because of heterogeneity in terms of topography, surface characteristics and variability of weather and climate conditions.…”
