Western Disturbances —extratropical storms originating in the Mediterranean Sea—move eastward, bringing light rain to the lowlands and significant snowfall (20-50 cm) to the high Himalayas. These are crucial for replenishing winter snowpack that feeds spring river flows.

An Analysis of Nepal’s Winter Season: Climatic Patterns, Regional Variations, and Socio-Economic Impacts | | Siwalik & Mid-Hills | 3°C –
Nepal, a country characterized by extreme topographical diversity ranging from the Terai lowlands (60m) to the world’s highest peaks (8,848m), experiences distinct seasonal cycles. The winter months in Nepal—traditionally spanning December, January, and February —represent a period of unique climatic stability, clear skies, but significant thermal contrast. Unlike the monsoon’s chaos or autumn’s mild perfection, winter presents specific challenges and opportunities for agriculture, tourism, and public health. This paper defines Nepal’s winter climatology and examines its regional disparities. and Socio-Economic Impacts Nepal
