Weather fact > > satellite cloud picture

Green means land, and blue means sea. (0.5) White indicates the cloud area. (0.5) The thickness of clouds is different in different regions. The whiter the cloud, the thicker it is. (0.5) The places with thick clouds are generally rainy areas. (0.5 points)

Test analysis: the color and weather of satellite cloud images: blue represents the ocean, green represents the land, and the blue-green area is sunny; White is a cloudy and rainy area. The thicker the white layer, the greater the probability of rainfall.

Comments: This question can also examine the two major elements of climate: temperature and precipitation. Weather: the atmospheric condition of a place in a short time. It is always changing; Climate: Generally, the average weather conditions in a place for many years will not change much. Two characteristics of weather: ① At the same time, the weather in different places is different; ② The weather in the same place at different times may be different. Wind direction, wind force and weather vane: ① Wind direction refers to the direction of the wind ② Wind force refers to the strength of the wind, which is expressed by the wind grade, with 1 ~ 12 wind; ③ The wide end of the wind vane indicates the wind direction, and the arrow tail points to the wind direction, that is, the big head blows the small head ④ The wind tail is on the right side of the wind pole. Weather forecast: forecast sunny and rainy days, wind and rain, temperature, etc. Weather symbol. Air quality: understand the content of air quality; Understand the meaning of air quality; Understand the index, grade and status of air quality.
