Answer the following questions of Geography :-
1.) What causes the development of mountain winds?
2.) What is ' Jet Stream ' ?
3.) What is Mistral?
4.) Where does Loo majorly blow?
5.) ' Seasonal changes in the natural regions are associated with the migration of pressure belts ' . Explain.
Answers
Explanation:
1. During the day, the sun heats up mountain air rapidly while the valley remains relatively cooler. Convection causes it to rise, causing a valley breeze. At night, the process is reversed. During the night the slopes get cooled and the dense air descends into the valley as the mountain wind.
2. Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds. Their paths typically have a meandering shape.
3. The mistral is a strong, cold, northwesterly wind that blows from southern France into the Gulf of Lion in the northern Mediterranean. It produces sustained winds often exceeding 66 km/h / 18 m/s, sometimes reaching 185 km/h / 51 m/s.
4. Loo is a strong, hot and dry summer afternoon wind from the west which blows over the western Indo-Gangetic Plain region of North India and Pakistan. It is especially strong in the months of May and June. Due to its very high temperatures, exposure to it may lead to heatstrokes.
5. Monsoon climate is the result of the shifting of pressure and wind belts. ... The NITC is withdrawn from over the Indian subcontinent and south-east Asia because of southward shifting of pressure and wind belts due to southward migration of the sun at the time of winter solstice.
