Synoptic principles and methods set

The collection of weather principles and methods is as follows:

I. Basic principles

1. Atmospheric circulation: Atmospheric circulation refers to the horizontal movement of the earth's atmosphere, including wind and air pressure. The motion of the atmosphere is influenced by many factors, such as the rotation of the earth and solar radiation.

2. Thermodynamic process: Thermodynamic process is a process in which meteorological elements such as temperature and humidity in the atmosphere change, including evaporation, condensation and precipitation. These processes play an important role in atmospheric circulation.

3. Dynamic process: Dynamic process is the process of the change of meteorological elements such as air pressure and wind in the atmosphere, including pressure gradient force and geostrophic deflection force. These processes have an important influence on the movement and change of the atmosphere.

Second, the basic method

1. observation method: meteorology studies the state and changes of the atmosphere by observing meteorological elements in the atmosphere, such as temperature, humidity, wind, air pressure, etc. Observation methods include ground observation, high altitude observation and satellite observation.

2. Numerical simulation method: Numerical simulation method simulates the movement and change of the atmosphere by establishing a mathematical model. This method can simulate complex atmospheric system, such as typhoon and rainstorm, and provide important basis for meteorological forecast.

3. Statistical analysis method: Statistical analysis method is to find out the statistical laws of the atmosphere such as climate change and meteorological disasters by analyzing historical meteorological data. This method can provide important reference for meteorological forecast and environmental protection.

Application of synoptics

1. One of the most important applications of meteorology is weather forecasting. By analyzing historical meteorological data, observation data and numerical simulation, meteorologists can predict future weather changes, such as temperature, humidity, wind speed and pressure. These prediction results are of great significance to agricultural production, transportation, energy utilization, environmental protection and other fields.

2. Agricultural production needs to understand the occurrence law of climate change and meteorological disasters, so as to take corresponding measures to improve the yield and quality of crops; Transportation needs to know the weather conditions in order to arrange flights and routes reasonably; Energy utilization needs to understand the changes of meteorological factors such as temperature and humidity in order to optimize energy utilization efficiency.

3. Meteorology also plays an important role in the field of meteorological services. Meteorological services include providing meteorological information for government decision-making, public services and enterprise production. Meteorologists can provide scientific basis for government decision-making by analyzing meteorological data and models.

4, such as formulating disaster prevention and mitigation policies, planning urban construction and transportation. ; To provide the public with meteorological information and consulting services such as meteorological forecast and early warning of meteorological disasters; Provide meteorological services for energy utilization, agricultural production and other enterprises.
