Why is the Himalayan region colder than the northern plains?
L S Rathore, former director general of the IMD, said fog factors differ in the hills and the plains. “The rays hit the hills first and there is more scope for the fog to dissipate. So, the temperature in the hills settles down after sunrise.
How cold does it get in the Himalayas?
The average summer temperature drops to 15°C and the average winter temperature is below freezing point at the middle range of the Himalaya Mountains. Over 5000 meters, the temperature is below freezing point all year round, and the mountain top is always covered by snow.
Why do polar regions not get colder?
When the sun is near the horizon, solar radiation is spread over a larger area. Thus, the intensity of solar radiation is far less at the polar areas than in the low latitudes. When the solar intensity is less the earth’s surface can not warm as rapidly.
How do Himalayas protect us from the very cold winds?
The Himalayas act as a perfect climatic divide in the following ways: The Himalayas act as a barrier to cold winds that blow from central Asia and thus prevent the Northern Plains from becoming freezing cold. The Himalayas act as a barrier to moisture laden South West monsoon winds.
Why Mangalore is not cold even in the month of December?
Mangalore is a coastal region which experiences moderate climate due to the influence of the sea. It does not experience extreme climate. Hence, Mangalore is not cold even in the month of December.
Are the Himalayas hot or cold?
The Himalayas experience a wide range of climate from humid subtropical in the lower regions to permanent snow and ice at higher altitudes. A wonderful time to be on holiday. The weather is consistently warm and sunny during the day and cold at night.
Why are cold regions cold?
But even during the polar day, the period of continuous sunlight, only a relatively small amount of solar energy reaches the Arctic or Antarctic regions due to the low angle of incoming rays. These two phenomena thus form the basis for sustained cold conditions in the northern and southern polar regions.
What is the climate of the northern side of the Himalayas?
The northern side of the Himalayas, also known as the Tibetan Himalaya, is dry, cold and generally, wind swept particularly in the west where it has a cold desert climate. The vegetation is sparse and stunted and the winters are severely cold. Most of the precipitation in the region is in the form of snow during the late winter and spring months.
What is the importance of the Himalayas in meteorology?
The Himalayas, as a great climatic divide affecting large systems of air and water circulation, help determine meteorological conditions in the Indian subcontinent to the south and in the Central Asian highlands to the north.
Why are there prolonged periods of day and night in Himalayas?
The prolonged periods of day and night over the North and South polar regions are not existing in the Himalayan region. But the outflow of cold from the Himalayas produces a steeper temperature gradient due to their extremely high altitude and proximity to the highly energetic tropical environment.
Which of the following mountain ranges border the Himalayas to the south?
The Himalayan range is bordered on the northwest by the Karakoram and Hindu Kush ranges, on the north by the Tibetan Plateau, and on the south by the Indo-Gangetic Plain.
