Nanjing somatosensory temperature

On August 12, 2022, the somatosensory temperature in Nanjing exceeded 40 degrees. 1 1 Nanjing Meteorological Observatory has released the fourth high temperature red warning signal this year, and it is estimated that the temperature in some areas of our city will rise above 40℃. Yesterday, the highest temperature of some automatic stations in Nanjing exceeded 40℃.

There are standards for temperature measurement. The observed temperature refers to the air temperature in the louver at a height of 1.5m from the ground. Nanjing Meteorology once explained that in the same city, due to the influence of underlying surface, surrounding buildings and vehicles, the temperature varies from place to place. In the summer with strong sunshine, the pavement temperature of cement road and asphalt road is often above 50℃.

The dark seat after exposure even reaches above 60℃, so the water temperature, ground temperature and car temperature measured by everyone are not equal to the temperature. Sometimes, the temperature is different from the perceived temperature, because the somatosensory temperature is not only related to the temperature of the atmosphere, but also related to humidity, wind speed, air pressure, solar radiation and so on.

Sometimes we think the temperature is the same as the temperature we feel, and sometimes we think there is a big difference. This is because the somatosensory temperature is not only related to the atmospheric temperature, but also related to humidity, wind speed, air pressure, solar radiation and even mood. For example, when the relative humidity is less than 45%, the influence of humidity on the somatosensory temperature can be ignored, but when the humidity is high, the temperature is higher than 24℃.

The somatosensory temperature will be significantly higher, the temperature will be lower than 15℃, and the somatosensory temperature will be significantly lower than the temperature. The influence of wind speed on somatosensory temperature is mainly that the greater the wind speed, the more beneficial it is to take away the body surface heat and feel cooler. However, some studies have shown that when the temperature exceeds 32℃, the greater the wind speed, the warming effect will occur.
