The temperature observation instrument of the meteorological instrument, how to measure the meteorol

Automatic weather observation instruments are also known as five-element measuring instruments.

Air temperature is a physical quantity that measures how hot and cold the air is, and represents the magnitude of the average kinetic energy of the movement of air molecules. It is usually expressed by the Celsius temperature scale (t), and also by the Fahrenheit temperature scale (f), and the absolute temperature (t) is commonly used in theoretical research work, and its conversion relationship is:

t = 5*( f—32 ) 9 t = t — ground air temperature generally refers to the atmospheric temperature at meters above the ground. When measuring, in order to prevent the influence of solar radiation on the observed values, the temperature measuring instrument must be placed in a louver box or radiation shield, and the measuring element must be well ventilated.

The main instrument used by meteorological stations to measure the temperature of the air near the ground is a glass tube thermometer containing mercury or alcohol. Because the thermometer itself has a greater capacity to absorb solar heat than air, the readings indicated under direct sunlight are often higher than the actual temperature of the air around it, so when measuring the temperature of the air near the ground, the thermometer is usually placed in a louvered box ventilated on all sides about the ground. The surface air temperature referred to by the meteorological department refers to the temperature in the louver box at about the height of the ground.

Meteorological instruments are used as meteorological pre-sources.

Professional equipment in the field of meteorological services such as newspaper and meteorological monitoring. It can be classified into two categories: surface meteorological observation instruments and upper-air meteorological detection instruments. There are mainly automatic weather stations, automatic rain gauge stations, wind speed and wind vanes, wind vane bags, shutter boxes, temperature and humidity recorders, sensors, wind vanes, wind speed alarms, wind energy anemometers, meteorological center software, GPRS wireless transmission modules, etc.

The temperature of the atmosphere is referred to as air temperature, and people usually use the size of the air temperature value to reflect the degree of cold and heat of the atmosphere. Our country uses the Celsius temperature scale.

i.e. , read as . Public weather forecast.

The temperature is measured on a thermometer in a louver box at a height of one meter above the ground in an observation field planted with turf. The average temperature refers to the arithmetic average of the temperature values observed in each excitation cave over a certain period of time.

Depending on the length of the calculation time, there may be the average temperature of a certain day, the average temperature of a certain month, and the average temperature of a certain year. The daily maximum temperature is the highest value of the temperature in a day, which generally occurs at 14 to 15 o'clock, and the lowest temperature generally occurs at 5 or 6 o'clock in the morning. The temperature items of surface meteorological observation include timed temperature, daily maximum temperature, and daily minimum temperature.

Comes with a thermometer.

The weather station should make a continuous record of the air temperature, taking one decimal place as a unit. The distribution of air temperature is usually represented by an isotherm diagram. The so-called isotherm is the connection line of various points with equal air temperature on the ground, and the different arrangements of the isotherms reflect the different temperature distribution characteristics.

If the isotherm is sparse, it means that the temperature is not much different from place to place. There are three main factors that affect the distribution of temperature, namely latitude, sea and land.

and height.
