Clouds and rain also cause changes in weather. The weather becomes cooler when it rains. In nature, water changes to water vapor due to heat. This process is known as evaporation. The water vapor cools off and this process is known as condensation. This cooled water vapor comes down as rain. This is the water cycle.
Meteorologists study weather and inform us about the weather in the coming days.
The information we get about weather is called the weather forecast. You can read it in newspapers or hear it on radio and television. Farmers, pilots and sailors use this information to plan, fishermen and chart their work.
Climate is the average condition of a place calculated for longer period of time. Different parts of the world experience different types of climates. Some regions are hot had wet throughout the year, others remain hot and dry. In some regions, it is always very cold and there is snow and ice all the time, while other areas experience it for some parts o the year. Some regions are cold but there is no snow. Still other parts of the world have a moderate climate –neither too hot nor too cold with a fair amount of rainfall.
Regions - climatic condition
a) North India - mountain: high mountains, like Himalayas, covered with snow ice through the year. Plains are very hot to very cold.
b) South India- warm and humid most of the year.
C) East India- desert are hot and dry.
You can see that India I quite unique because it has almost every kind of climatic condition.
The climate is affected by several factors. Some are these.
1) Altitude (height): mountain receives more rainfall than low-lying areas. The temperature on top of mountains is much less than the temperature in low –lying areas. The higher the place, the colder it will be. That is why you often see snow on the top of mountains all year round.
2) Distance from the sea: places near the sea are warmer in winter and cooler in summer compared to places further inland.
3) Humidity: the extent of water vapor or moisture in the air, also known as humidity, is another important factor. The more the humidity, the greater the rainfall in the region.
The climate of a region decides the kind of life the people of that region. Their clothing, food, shelter and even occupations, especially agriculture and the kind of crops grown, are decided by the climate. All this adds to the importance and culture of the place.
Foe example, in the very cold northern states of India fruits like apples and peaches grow. The snowy mountain slopes of the Himalayas are good for sports like skiing and mountaineering.
The low –lying areas which are near the sea like Goa have good weather and so attract a lot of tourists.
The states of north India like Punjab grow wheat which needs cold but a less rainy climate, while the states of the south grow rice which needs hot and rainy climate.
