在山区,一般海拔高度每升高100米,气温就会降低0.5℃～0.6℃,所以高处不胜寒。然而,在海拔高度为300米～400米的丘陵地带的南坡,温度最高地段不在山脚,也不在山顶,而在山腰。在山腰有一个气温高于平地和山顶的逆温层。1991年12月29日,新邵县出现了大雪降温天气,气温从8.8℃陡然
In mountainous areas, the temperature will drop by 0.5 ℃ ~ 0.6 ℃ for every 100 meters elevation above sea level, so the altitude is above freezing. However, on the southern slopes of the hilly terrain 300 to 400 meters above sea level, the highest temperature is not at the foot of the mountain, nor at the top of the mountain but at the mountainside. In the mountainside there is a temperature above the ground and the top of the inversion layer. December 29, 1991, Xinshao County appeared heavy snowfall weather, the temperature suddenly dropped from 8.8 ℃
