Weather is the condition of the air that surrounds the earth. The weather
ay be hot or cold, cloudy or clear, windy or calm. It may bring rain, snow.
We wear clothes depending largely on the weather. We put on heavy
lothes when it is cold and dress lightly when it is hot. We also heat our homes
in cold weather and cool them in hot weather. Our mood also depends on the
weather.
The weather has a great impact on agriculture. Farmers need clear weather
to plant and harvest their crops. A storm or a sudden frost can damage or kill
much harvest.
Weather is not the same as climate. Weather is the condition of the air
during a brief period. A region's weather may change greatly from day to
day. But the average temperature and the amount of rain and snow remain
about the same from year to year.
People have tried to predict the weather for thousands of years. Today,
scientists use complex instruments such as radar, satellites, and computers to
forecast the weather. The forecasts are broadcast on radio and television
stations and published in newspapers.
