Why does it feel cold?
Night skies caused by radiation heat loss and complement the cold air in during the day yesterday, resulting in cold weather yesterday
Affect the crops?
Recent temperatures have been relatively low, but overall smooth, properly belongs to the cold air, crops bear
Yesterday was the "rain" solar terms, Chengdu a gloomy weather, rain to the party. According to the monitoring of the professional observatory in Sichuan Province, Chengdu yesterday only 7 ° C maximum temperature, minimum temperature to 4 ° C, minimum and maximum temperatures than the day before yesterday, only to rise by 1 ° C temperature and not, as the day before yesterday forecast a significant pickup. Cause such two reasons: the night clear sky radiation heat loss, and during the day to supplement the cold air.
Managing the Chengdu temperatures gradually rise, the good weather will continue until the 24th.
Maximum temperature 7 ° C the people refer to "cold"
Yesterday afternoon, the work of Wang Hongxing Road, hurried out, think a few days ago Chengdu has been cloudy, weather yesterday, the temperature rose significantly, so she was wearing a thin sweater and coat and went out. I did not realize just go out, a burst of cold wind hit, Wang can not help but hit a chills, could not help the neck indentation clothes. Walking down the street and saw a lot of people put on a thick down jacket, wearing a scarf and gloves, overnight, was back at the winter season when the north wind whistling.
Chengdu yesterday's maximum temperature is 7 ° C, 2 o'clock yesterday afternoon, the lowest temperature only 4 ° C, there in the 7 o'clock yesterday morning, the temperature difference of only 3 ° C, rain macs next day, feeling very cold. "Is not said to be warming, how also from the rain?" Some doubts of the public.
Sichuan professional weather experts said the cold air on the day before the end of monitoring, Chengdu yesterday should be overcast to cloudy weather. Unexpectedly, the cold air to retreat does not completely as expected in as. The day before yesterday night, Chengdu is indeed a rare period of clouds, the weather was sunny than a few days ago, however, not only did not let Chengdu warming, the clear sky radiation surface temperature to redouble loss. Yesterday during the day, under the influence of residual cold air and the supply of cold air, the clouds of the Chengdu air increased, the sun does not come in, Chengdu warming fatigue. Coupled with the role of the evening cold and warm air masses, the formation of rain is to accelerate the reduction of the temperature.
This winter sunshine than normal years
However, experts say, will be completely over the cold air in the night yesterday. Since yesterday night, the weather in Chengdu gradually became cloudy. Due to the clear sky radiation, morning temperatures are still low, but the afternoon, due to sun exposure, Chengdu is the highest temperature will rebound to 10 ° C. The experts said that Chengdu in the winter as long as there is no light, it is difficult to heat up, even if the warm air mass; the contrary, the arrival of the warm air mass encountered remnants of cold air, the formation of rainfall to the ground and then evaporate away heat, Chengdu, but will cool down. Cold air, Chengdu also cooling, this is winter, a common phenomenon.
No light it is difficult to heat up, this is a common phenomenon in Chengdu. In fact, this winter, although no strong cold air Sichuan cooling, but in most parts of Sichuan, light indeed compared with previous years less. According to the records of the Climate Center of Sichuan Province, by the rainy weather, most parts of the basin from December last year to now, sunshine cumulative duration more than 20 to 150 hours, compared with historical average of 3 to 8 percent. Southwest Sichuan mountain most of the western Sichuan plateau most sunny days more sunshine hours in most parts of 180 to 600 hours, compared with the same period the year, less than normal for about 1 percent. December last year to now, most of the parts of the province basin temperature change is relatively stable, strong freezing weather process, the average daily temperature is below 3 ° C the number of days except 5 to 13 days of the surrounding mountains of the basin, most of the rest of less than three days. Most of the remaining period, around the average daily temperature is mostly maintained at between 5 ~ 8 ℃.
