Huasheng Online December 14 (Reporter Lai Yongyuan) Today, the reporter learned from Hunan Provincial Meteorological Bureau that today and tomorrow (day from the 14th to the 15th), Hunan Province is mainly cloudy during sunny days, and affected by strong cold air on the ground and weak fluctuations in high altitudes tomorrow night to the day after tomorrow, Hunan North , local areas will be sleet or snow. At the same time, Gemini Meteor Shower will also be of great value tonight. You might as well take advantage of the sunny weather and watch it together.
Hunan Provincial Meteorological Observatory predicts that today and tomorrow will be controlled by high-altitude northwest airflow. The province will mainly be cloudy during sunny days. Tomorrow night to the day after tomorrow, the wind will increase to level 4 to 5, local gusts will be level 7, and local sleets will be sleet or snow in northern and central Hunan. In terms of temperature, the cold air is active, and the temperature is about 2℃ lower.
Meteorological experts remind that we should pay attention to preventing the adverse effects of strong winds from the evening of the 15th to the 16th on water transportation, outdoor facilities, temporary buildings and agriculture. Northern Hunan needs to prevent the risk of road icing; the temperature is low and the electricity load increases, and energy supply needs to be ensured, and the public should pay attention to the safety of heating, fire and electricity. In addition, the minimum temperature on the morning of the 17th was below 0℃, and urban sprinkler operations must be stopped. Continue to do a good job in water conservation, water retention and scientific water use; while ensuring safety, carry out artificial rain-increasing operations in a timely manner.
At the same time, the Gemini meteor shower will also usher in a maximum value at 21:00 tonight (December 14), with an hourly 100 niche traffic per hour. This is one of the three major meteor showers in the northern hemisphere, and it is also the largest traffic among the three meteor showers, with a relatively stable scale. The radiation point rises from the northeastern direction after night, and is almost unaffected by moonlight in the first half of the night, making it an excellent opportunity to watch the meteor shower.

According to Tan Wei, president of Hunan Astronomical Association, Gemini meteor shower originates from particles in the orbit of the near-Earth asteroid Faeton (3200 Phaethon). Since the radiation point of this meteor shower is near Gemini , it is called Gemini meteor shower.
"To enjoy the magnificent astronomical landscape, you can choose suburbs or places with less light pollution, which is easier to see." Tan Wei said that generally speaking, only 50-60 kilometers away from large cities can you see a clearer meteor shower landscape. Because the temperature is low in winter, it is easy to catch a cold and cause discomfort. Pay attention to adding clothes to keep warm.
In autumn and winter, Nanyue Hengshan, Yueyang Fushou Mountain, Yongzhou Yangming Mountain and Zhangjiajie are all good choices to watch meteor showers. Around Changsha, Dawei Mountain, Hei Mi Peak, Shenxianling Wind Power Farm, etc. are closest to Changsha urban area and are also more suitable for observation.
