Solution of Meteorological Terminology (Terminology)

I believe that many friends who study meteorology or are interested in meteorology will often see some professional articles. If Chinese is easy to understand, but if you encounter foreign literature, it may involve many technical terms, such as many nouns. The author searched a lot of information in this area, and now I will explain it to you.

English meteorological term: STN-WBAN: weather station number.

YEARMODA: year, month and day.

Temperature: temperature

DEWP: dew point

SLP: sea level pressure.

STP: station pressure.

VISIB: visibility

WDSP: Wind direction (wind direction; Speed)

MXSPD: maximum wind speed (maximum. Speed)

Gust: gust

Max: Max.

MIN: minimum value

PRCP: precipitation

SNDP: snow depth

FRSHTT: Did it happen that day (1 means it happened, and 0 means it didn't happen).

Meteorological related nouns

Meteorology: As the name implies, weather phenomena, in layman's terms, are all physical and chemical conditions such as wind, rain and lightning in the sky. These phenomena are determined by variable factors, such as the interaction of temperature, air pressure and gradient.

Weather: refers to the conditions that affect the short-term meteorological characteristics of human activities. For example, we said, "Yesterday it was clear in Wan Li, but today it is overcast and stormy." This is what we call the weather.

Climate: refers to the long-term characteristics of meteorological conditions of the earth or a certain area in a year or a period of time. For example. Dali has four seasons like spring; Hainan has four distinct seasons, neither hot in summer nor cold in winter, with small annual temperature difference and high annual average temperature, which belongs to tropical monsoon climate.

Meteorological factors

There are mainly six factors, air pressure, temperature, humidity, wind speed, precipitation and sunshine.

1, air pressure

That is, the pressure of atmospheric pressure column per unit area. There are two kinds of air pressure units, one is expressed by low mercury column; Another unit that we often hear in weather forecast is "Pa", which is the international system of units for barometric pressure. 1 Pa means that the area of 1 m2 is subjected to the force of 1 Newton.

2. Temperature

That is, the temperature of the atmosphere, internationally expressed in degrees Celsius.

3. Humidity

Humidity can reflect the degree of atmospheric humidity. Generally expressed by water vapor pressure, absolute humidity and relative humidity. Absolute humidity refers to the density of water vapor, that is, the mass (grams) of water vapor contained in the atmosphere per cubic meter; Relative humidity is the percentage of actual vapor pressure and saturated vapor pressure at that time.

4. Wind speed

Wind speed should be what we can feel most and what we are familiar with. Atmospheric flow is similar to water flow, from high pressure to low pressure. Wind speed is generally measured in meters per second and can be divided into 12.

Step 5 precipitate

Water is the source of life and the foundation of life on earth. Water makes our survival possible. When water vapor condenses and falls from the clouds to the ground, this process is precipitation. Common rain and snow belong to precipitation, as well as hail, ice beads and showers. The measurement of precipitation is generally based on the falling height (mm) per unit time.

6. Sunshine

Cloudiness and sunshine are climatic factors representing the sky conditions. Sunshine is affected by cloud cover, and the international unit of sunshine is watt/square meter or milliwatt/square meter. The atmosphere is changing all the time, with average value, maximum value and minimum value every day, and it affects the daily temperature.
