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 a wind of 1 ~ 12; 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.
