They also affect the amount of rainfall if they are very high. The relief of a place affects the climate of a place when the high mountains act as barriers for cold and hot winds, e.g. How does the relief of an area affect the climate of a place? The two types of ocean currents are warm currents and cold currents. Ocean currents are streams of water that move in the same direction throughout the year. What are ocean currents? Name the two types. The latitude and the altitude of the place affect the temperature and rainfall of the area. Which two factors affect the wind and pressure system of an area and how? This is because the air density decreases with height. The temperature of air decreases at the rate of 1☌ for every 165 m of ascent. How does the temperature decrease with altitude? The temperature decreases from the equator to the poles. The amount of solar radiation varies with latitude because of the curvature of the earth. Why does the amount of solar radiation vary with latitude? very hot in summers and cold in winters, e.g. There is general decrease in the amount of rainfall from east to west in the Northern Plains as the winds have less moisture in them when they reach the western side.Īs the distance from the sea increases the moderating influence of the sea decreases and the people experience extreme weather conditions.
Why is there decrease in rainfall from east to west in the Northern Plains? The coastal areas experience less contrast in temperature because of the influence of the sea, e.g. Why do the coastal areas of India experience less contrast in temperature? Most parts of India receive rainfall from June to September. In which months is the season of rainfall experienced in India? The annual precipitation is over 400 cms in Meghalaya and less than 10 cms in Ladakh and western Rajasthan. What is the variation of annual precipitation in India? In winter, the temperature in Drass in Jammu and Kashmir is as low as – 45☌ and Thiruvananthapuram may have 22☌. What is the variation of temperature in winter in India? In summer, the mercury occasionally touches 50☌ in some parts of Rajasthan desert, whereas it may be around 20☌ in Pahalgam in Jammu and Kashmir. What is the variation of temperature in summer in India? It refers to the seasonal reversal in the wind direction during a year. The word Monsoon is derived from the Arabic word ‘mausim’ which literally means season. India’s climate is described as “Tropical Monsoon Type of Climate”. Name the elements of climate and weather.Įlements of weather and climate are temperature, atmospheric pressure, wind, humidity and precipitation. Weather refers to the state of the atmosphere over an area at any point of time. Ĭlimate refers to the sum total of weather conditions and variations over a large area for a long period of time (thirty years).
