Shaanxi welcomes -cliff-like- cooling and issues blue frost warning

On October 20, in a recent update from the Shaanxi Provincial Meteorological Station, it was reported that the region is expected to face precipitation, a drop in temperature, and windy conditions due to the combined effects of a plateau trough and cold air. Specifically, the eastern part of Shaanxi’s northern region and some areas in the southern part are anticipated to experience a temperature decrease of 4 to 6 degrees Celsius, while parts of eastern Guanzhong and southern Shaanxi may see drops of 6 to 8 degrees Celsius.

In Xi’an, the capital of Shaanxi, reporters observed a stormy atmosphere with a significant temperature drop prompting many residents to bundle up in winter clothing and scarves. According to the Xi’an Meteorological Station, the city has been under the influence of strong cold air since the evening of October 19, and temperatures continue to fall, with daily averages dropping between 8 to 10 degrees Celsius. The lowest temperatures are expected early on October 21, accompanied by brief gusts of wind reaching 6 to 7 on the Beaufort scale.

At 9:30 AM on the same day, the provincial meteorological authority issued a blue frost warning. As a result of cold air mass and radiative cooling, from 2 AM to 9 AM on October 21, and again from 2 AM to 9 AM on October 22, areas like most of Yulin, Yan’an, central Tongchuan, northern Xianyang, parts of eastern Shangluo, and some locations in the Qinling Mountains could see minimum temperatures drop to between -2 to 0 degrees Celsius. Notably, on October 22, regions in western and northern Yulin and western Yan’an may experience temperatures falling below -3 degrees Celsius, which could pose a risk of frost affecting key seasonal crops.

Meteorological departments are advising government and agricultural authorities to prepare for frost conditions. Farmers are recommended to take protective measures for crops, vegetables, flowers, fruits, aquatic farming, and forestry. Local rural organizations and farmers are encouraged to stay vigilant about local frost warning information to enhance protective actions.

Additionally, at 8 AM, the Shaanxi Provincial Meteorological Station released a weather bulletin indicating light rain across parts of northern Shaanxi and most of Guanzhong, with eastern northern Shaanxi and eastern Guanzhong experiencing light to moderate rain, while the northern regions of Shaanxi and the Qinling Mountains are facing light rain or sleet.
