Climate in Nepal remains sub-tropical monsoon with its geographical features. Nepal's temperature decreases at a general lapse of 6 degrees centigrade at every 1000 meters ascent. Terai ranges 57.3 meters to the Himalayan region 8848 meters above the sea. South facing mountains record high temperature, which receives more rainfall as compared with north-facing mountains. North and west movement from the Bay of Bengal's moist air caused monsoon in Nepal. The westerly air's misty also caused a winter monsoon. The Himalayas receive snowfall and lower regions accept rainfall in the country.
Climate in Nepal recommended warm, cool, and cold temperatures with its four seasons. Autumn months, September, October, and November remain a little bit cold and clear weather. Winter months December, January and February stay coldest with Snowfalls in the high Himalayas. Spring months, March, April, and May remain a warm temperature with dusty and windy. Summer months, June, July, and August receive heavy rainfall, wet and hot temperatures. Kathmandu Valley remains average summer and winter temperatures of 19°C- 35°C and 2°C to 12°C.
Climate in Nepal may effect by a landscape, altitude, mountain face, the distance of a sea, the mountain's sloppiness and the forest types. Every year Nepal's monsoons washed up fertile soils into the Bay of Bengal. Lumle (nearby Pokhara) described as the rainiest area of Nepal receive annual 556-centimetre rainfall. Mustang recorded the lowest rainfall area of Nepal that receive annual 25-centimetre rainfall. The country can be divided into five physiographic zones, Terai, Siwaliks, Middle Mountains, High Mountains and High Himalayas. Nepal is divided into five types of climate, which is below.
Subtropical monsoon climate (60 m to 1200 m)
Subtropical monsoon climate remains in the southern parts of Nepal, including Terai, Bhabar, Inner Terai, and Churia. Summer temperature remains 34° Celsius to 42° Celsius and winter temperatures will be 6° Celsius to 9° Celsius. The average rainfall will be 100 to 200 centimetres. The climate is useful for rice and jute.
Warm temperate monsoon climate (1200 m to 2100 m)
The warm temperate monsoon climate remains in Churia, and Mahabharata Lake with a hill and valley. Summer temperatures will remain between 24° Celsius to 30° Celsius and winter temperatures will be 3° Celsius. Average rainfall will be 100 centimetres to 125 centimetres. Fog will be common in winter.
Cool temperate monsoon climate (2100 m to 3300 m)
Cool temperate monsoon climate remains at the highest elevation in the Mahabharata and lowers the elevation of the Inner Himalaya. Summer temperature remains between 15° Celsius and 20° Celsius. The winter temperature will be Zero° Celsius. The average rainfall will be 50 centimetres to 100 centimetres.
Alpine climate (3300 m to 5000 m)
The Alpine climate remains at the highest elevation of the inner Himalaya and the lower elevation of the Greater Himalaya. Cold wind usually blows there. Summer temperature will be 10° Celsius to 15° Celsius and winter temperature will be -5° Celsius to -10° Celsius. Average rainfall will be less than 50 centimetres. The climate is useful for herding and tourism activity.
Tundra climate (5000 m to 8848 m)
Tundra climate remains in the snow line (5000 m) mountain. The temperature will be cold. Snow usually falls rather than rain. The temperature will be below Zero° Celsius. Air will be thin. Snowstorms are run very frequent in the afternoon. Oxygen will available around 35 % or less only.
