The way people look at the weather

Folk ways to watch the weather are: observing clouds, observing animal behavior, observing plants and so on.

1, observation cloud

Clouds are an important indicator to predict the weather. If there are dark clouds in the sky, it is likely to rain. If the clouds are red or orange, there will probably be a storm. If there are cumulus clouds in the sky, there is likely to be cold air coming.

2. Observe animal behavior

Animal behavior can also predict the weather. For example, if birds fly high in the sky, there will probably be good weather. If ants are busy on the ground, it will probably rain. If the cattle get together, there is likely to be a storm.

Step 3 observe plants

Plant growth can also predict the weather. If the leaves of plants are facing up, it is likely to be sunny. If the leaves of plants are facing down, it is likely to rain. If the flowers of the plants are closed, there is likely to be a storm.

Forecast method of weather forecast:

1. Numerical weather forecast model: This is a method to simulate the future weather by using mathematical models and a large number of observation data. By collecting meteorological data and meteorological phenomena and inputting them into numerical models, the future meteorological changes are calculated by using physical and mathematical equations. These models can predict various meteorological phenomena, such as temperature, wind speed, precipitation, clouds and so on.

2. Satellite images: Satellites can provide the global weather conditions of the earth. Through satellite images, we can observe the changes of meteorological phenomena such as clouds, wind direction and wind speed, so as to predict the future weather conditions.

3. Weather radar: Weather radar can observe meteorological phenomena such as precipitation, clouds and wind speed by emitting electromagnetic waves. By observing the electromagnetic wave signals returned by weather radar, we can judge the intensity, position and shape of meteorological phenomena, and then predict the future weather conditions.

4. Observation by weather stations: By measuring atmospheric pressure, temperature, humidity, wind speed, precipitation and other meteorological parameters, weather stations can monitor weather conditions in real time, thus predicting future weather conditions.
