What do you usually record in the weather calendar?

Record the date, time, cloud cover, precipitation, temperature, wind direction and wind speed in the weather calendar.

On the weather map, analyze the weather system and atmospheric state of a certain area. This includes barometric analysis. Use isobar or contour line to represent the spatial pressure distribution and analyze the temperature.

The distribution of cold and warm air masses in the atmosphere, the thermodynamic structure and humidity analysis of the atmosphere are all expressed by isotherms. The distribution of water vapor content in the atmosphere is represented by equal specific wet line or equal dew point line. Wind field analysis. The characteristics of atmospheric flow are expressed by streamline and isowind. On the basis of these analyses, air mass analysis, frontal analysis and air pressure system (or wind field system) analysis can be carried out.
