观测记录和重建树木年轮反映了前季风（3月至5月）的温度冷却在西喜马拉雅山脉在后半部分的世纪。最低温度的快速下降速度大约是当地气候记录中最高温度上升速度的三倍，这是造成季风前平均温度冷却趋势的原因。日较差的增加归因于该地区大规模的森林砍伐和土地退化，并显示了当地强迫因子对气候的影响，与北方半球高纬度地区的总体趋势相反。
Observational records and reconstructions from tree rings reflect premonsoon (March to May) temperature cooling in the western Himalaya during the latter part of the 20th century. A rapid decrease of minimum temperatures at around three times higher rate, as compared to the rate of increase in maximum temperatures found in local climate records is responsible for the cooling trend in mean premonsoon temperature. The increase of the diurnal temperature range is attributed to large scale deforestation and land degradation in the area and shows the higher influence of local forcing factors on climate in contrast to the general trend found in higher latitudes of the northern Hemisphere.
