The Geographical Area of Nepal is divided into three Geographic regions
1. Himalayan region
The northern Himalayas are important for understanding Nepal's entire ecosystem because they not only represent special climatic conditions. The Himalayas serve as a barrier to the chilly winds that originate in Central Asia in the winter, defining the southern boundary of the monsoon wind patterns. 15% of the total land of Nepal is covered by the Himalayan region. The Subarctic and arctic climatic zones belong to the Himalayan region of Nepal. Due to the harsh weather, particularly in the winter, the majority of the Himalayas are inhospitable. In the lower areas of this region, summers are often mild but winters can be extremely cold.
2. Hilly region
The hilly region of Nepal is different from temperature and sub-tropical climate zones. This region covers 68% of the total land of Nepal. This region is more comfortable for living in because of the mild climate. The midlands are lovely all year long, however, the temperature of this region gets cool in the morning and at night. The average temperature in summer is 18 ° C to 35 ° C and 1 °C to 12 ° C in winter. Due to the interaction of monsoon winds with the Annapurna mountain, the Pokhara Valley in this area receives the most rainfall nationwide. The Hilly region has the highest amount of rainfall all over Nepal.
3. Terai region
Terai is a lowland area that lies in the southern part of Nepal. It is tropical and humid weather. 17% of land covers the total area of Nepal. Terai is the hottest part of Nepal where the temperature in winter is 6 ° C to 21 ° C and the temperature in spring/summer increases from 35 ° C to 38 ° C. The rainfall of the eastern part of Terai is extensive and the western part of Nepal is drier. The eastern Terai region of Nepal experiences widespread rainfall, with Biratnagar receiving between 70 and 75 inches (1,800 and 1,900 millimeters) of rain annually, whereas Mahendranagar experiences drier conditions with 30-35 inches of rain annually. In addition, this area has frequently seen the Loo (a hot, dry summer wind) as well as other natural disasters.
