The temperature is rising day by day, and the Shenzhen Meteorological Observatory lifted the yellow warning signal for cold land in the city at 15:00 on January 29, 2024.
But
Sitting in the room for the past two days
I still feel "frozen hands and feet"!
Many netizens said that they missed the sun very much
and issue a "soul torture"
Why didn't you feel warm
Instead it seems to be colder?
What about the heating up that was said before?
In fact
Temperatures are indeed rising
It's just that the recovery is relatively slow
Appeared since January 24th
After the lowest temperature during the cold spell
From the 25th
Shenzhen Futian National Basic Weather Station
The minimum temperature has generally risen
△ The lowest temperature at the National Basic Meteorological Station in Futian, Shenzhen, from January 24 to 29
however
The cold has continued to feel in the past few days
It is mainly related to two factors
The lag of changes in indoor air temperature
People's perception of temperature in indoor activities is sometimes different from the weather forecast data, because the change of indoor temperature has a lag, and indoor heating and cooling are later than outdoor ones. Specifically, it depends on factors such as the tightness of the room, the orientation, and the thickness of the walls and windows, and the better the seal, the slower the heat exchange with the outside air temperature.
If you closed all the doors and windows yesterday, it would still be warm indoors, and you could even wear short sleeves to move around the house, and similarly, when the temperature rises, it will feel slower indoors.
For example, it was predicted that the temperature would gradually rise, but it may have just dropped in the room at that time, and the temperature rose "half a beat slower", so it will make people feel that it is still very cold indoors.
Feel the temperature lower
From the National Basic Weather Station in Futian, Shenzhen
Statistics for the past five days
Air humidity is increasing
There are less than 5 hours of sunshine per day
This results in lower perceived temperatures
△ Average relative humidity at Futian National Basic Meteorological Station in Shenzhen from January 24 to 28
△ Total sunshine at Futian National Basic Meteorological Station in Shenzhen from January 24 to 28
Somatosensory temperature refers to the temperature at which the human body perceives the air, which can be different from the temperature of the actual environment. The perceived temperature is affected by factors such as wind, humidity, sunlight, and individual differences.
The air temperature in the weather forecast represents the degree of cold and warm air, while the perceived temperature represents the body's perception of the cold and warm environment. When the temperature is lower than 15°C, the higher the relative humidity, the colder it feels, hence the term "wet cold".
So
Although the temperature has slowly risen in recent days
But due to the lag of indoor temperature changes
and perceived lower temperatures
As a result, everyone feels that the recovery is not obvious
But
Temperatures are indeed rising
And with the strengthening of warm and humid air currents
Rain and fog will gradually increase in the coming period
The risk of returning to Nantian around the 30th is also increasing
Specific forecasts
- Today (30th) is cloudy with scattered light rain;
- From the 31st to the 2nd of February, the weather was warm and humid, with light fog or fog in the morning and evening, which may be accompanied by the phenomenon of returning to the south;
- Looking ahead, February 3-5 will be cloudy with light rain.
Wen Xin reminded
1. The rainy and foggy weather is gradually increasing, the visibility is low some time, and the road surface is slippery, please pay attention to traffic safety.
2. Pay attention to closing the windows. When the humidity comes, remember to keep the windows of your home closed. In particular, the windows facing south and southeast do not give humid air a chance to sneak in, and open them when the north wind blows.
3. Pay attention to moisture-proof. You can purchase some desiccant, moisture absorption box and other supplies in advance, and the reasonable use can remove the moisture in the home to a certain extent, and you can also spread newspapers on the floor or floor tiles, which have a good water absorption effect and anti-slip effect.
For those of you who are about to go home, please note:
According to the latest forecast of the Central Meteorological Observatory, from January 31 to February 5, there will be a wide range of continuous rain, snow and freezing weather in the central and eastern parts of the mainland, and there will be heavy snowfall or heavy snowfall in 10 provinces, and the cumulative snowfall in Henan, Shandong, Hubei and other places will be extreme; freezing rain will occur in five provinces of Henan, Hubei, Anhui, Hunan, and Guizhou, and the rain in the south of the Yangtze River will not be weak, accompanied by thunder and lightning.
Due to rain and snow
It is the peak season of returning home for the Spring Festival
And rain, snow and freezing weather have a negative impact on roads, railways, aviation, etc
will have a big impact
It is recommended that everyone follow the weather forecast
Arrange the itinerary reasonably and travel safely~
