How to check the historical weather temperature and humidity, the key is humidity, thank you!

Then you have to buy a temperature and humidity recorder. It depends on whether you are home or in the factory, generally buy a *** point for the general household, you can use it for a long time, the brand is looking for yourself, I have bought one before to give to foreigners, the kind with better quality, about three hundred, zoglab, it looks quite high-end, foreigners like it very much, for your reference.

Weather Post-Report Network can provide historical weather Simple and clear Weather conditions, temperature, and wind are available, but there is no humidity.

1. National Climate Center.

2. Xihe Energy Big Data Platform.

China Meteorological Administration.

4. China Education and Research Computer Network.

5. China Weather Network.

Step 1: Select a geographic location. You can choose either single-point data or regional average data.

<>Step 2: Confirm the data source. Historical data can be selected from Xihe Data Source, European Medium-Range Weather Center, NASA; **Data can be selected from the German Meteorological Office.

The temperature and humidity meter on the left indicates the temperature, which was 38 C at that time; The indication on the right is the humidity, which was 55% at that time.

Hygrometers are used to determine the temperature and humidity of the environment to better determine the environmental conditions for product production or storage. It is also often used in people's daily life and is widely used. When there is a lot of moisture in the air, we say that the air is moist.

Temperature and humidity meters play an important role in life, but there are many kinds of data on the table, which can easily be dazzling.

First, let's distinguish between the various numbers on the temperature and humidity table.

1. Temperature: Temperature, Humidity Display, Temperature Switching Display, Clock and Calendar Display.

2. Humidity: RH, this humidity refers to the percentage of water vapor (water vapor pressure) contained in the air and the amount of saturated water vapor (saturated water vapor pressure) under the same condition as air.

3. Hour time signal and daily alarm clock function. 12 24-hour clock.

4. Max min temperature and humidity memory function.

Secondly, different venues have different requirements, for example, some food refrigerators will be relatively cooler and drier than at home. Want to get a clearer idea of which humidity is best suited?

1. The most suitable environment for the human body: thermometer 18 25, relative humidity 47%RH 75%RH;

2. Living environment: 40%RH 70%RH;

3. Libraries, art galleries and museums: 40%RH 60%RH;

4. Computer computer room, communication room: 45%RH 60%RH;

5. Storage of clothing, cotton and wool textiles: 40%RH 60 RH;

6. Storage of dairy products: 50%; rh~70%rh;

7. Fruit storage 60%RH 70%RH;

8. The most favorable environment for antiseptic and treatment: 30%RH 50%RH temperature and humidity table Of course, the appropriate humidity is not constant. Because relative humidity is related to temperature, the higher the temperature, the greater the absolute humidity.

Therefore, the loudness and humidity required are different at different temperatures.

Modern medical meteorological studies have shown that the most suitable relative humidity for the human body is: when the room temperature is 25 in summer, the relative humidity is controlled at 40%-50% and is more comfortable; In winter, when the room temperature is 18, the relative humidity is controlled at 60%-70%.

I hope that through some of the above data, you can better understand how to read the temperature and humidity meter. This is just the usual data, some temperature and humidity meters, some places require more, and the data will be subdivided into more types, so as to make better use of temperature and humidity meters. If you do need to buy a temperature and humidity meter, you can buy a temperature and humidity meter with different functions according to the requirements of your place of residence or your own office.

You can pay attention to the weather forecast of the local TV station every day, and pay attention to the air humidity in the local area. The lower the humidity of the air, the more dry ,.. the weather indicates

You can dial ** to inquire, now the number of Know-it-all can check the weather conditions, and some areas also have their own weather queries**,..

You can install an air humidity tester in your home to test the air condition. When the weather is dry, you need to water the plants at home ,..

When you go out in winter, you should pay special attention to the weather and humidity. High humidity in the air causes particulate matter to absorb water, which can lead to further progress.

Relative air humidity refers to the ratio of the vapor pressure of water in the air to the saturated vapor pressure of water at the same temperature and pressure. There is no functional relationship between the absolute humidity of the air and the relative humidity of the air. For example, the higher the temperature, the faster the water evaporates, and the amount of water vapor in the air increases.

So throughout the day, it is often the middle of the day when the absolute humidity is greater than at night.
