My First Questions About Weather


What is weather?

Weather is the mix of events that happen each day in our atmosphere with respect to heat or cold, wetness or dryness, calm or storm, and clearness or cloudiness. Weather involves more than rain, snow, clouds or the sun. It involves things we can’t see like air pressure, wind, solar radiation or humidity. But weather is not the same everywhere.


Climate is the average weather pattern in a place over many years. The climate in your place on the globe controls the weather where you live. Scientists say climates are changing because the Earth is warming.

Does this contribute to global warming?

It may, but global climate change is more complicated than that. A change in the temperature can cause changes in other weather elements such as clouds or precipitation.

Who studies weather?

A meteorologist.

Why do we need to study weather?

We have different seasons and the weather affects our everyday lives. People like farmers, fishermen, pilots, construction workers need to know more about the weather to help them to decide how to carry out their duties. And even you! When you are going on a vacation, you will also need to know the weather of the place you are going . Before technology, people made forecasts by studying the clouds.

How do we observe weather now?

We use a thermometer to measure temperature, a barometer to measure air pressure, a rain gauge to measure precipitation, an anemometer to measure wind speed, a satellite to take pictures of clouds from space and a radar to see where and how much rain is falling.

What determines our weather?

All of our weather comes from basically two things: the sun and the moisture in the air. These two work together to form clouds, to make rain and thunderstorms and to cause winds to blow.

What has the sun got to do with the weather?

The sun emits energy at an almost constant rate, but a region receives more heat when the sun is higher in the sky and when there are more hours of sunlight in a day. The high sun of the tropics makes this area much warmer than the poles

The sun is the engine that drives the motion of water in our atmosphere. This movement of water is called the water cycle, which is also known as the hydrologic cycle. It involves the continuous circulation of water in the atmosphere through evaporation, transpiration, condensation, precipitation, and runoff (check their meanings).

Why does the wind blow?

The wind blows because air has weight. Cold air weighs more than warm air, so the pressure of cold air is greater. When the sun warms the air, the air expands, gets lighter, and rises. The wind usually blows from areas of high air pressure to areas of low pressure. If the high pressure area is very close to the low pressure area, or if the pressure difference is very great, the wind can blow very fast. —To Be Continued
