昆明静止锋是大气环流在特定时间(冬季)、特定位置(云贵高原东部)、特定地形的共同影响下,所产生的一种特殊气象特征。为了让学生全面理解静止锋形成的道理,首先,对照地图认识云贵高原在北纬23°—30°,处于西风带南侧的纬度位置上。冬季,风带、气压带随太阳直射点南移而南移的特点。第二步、认识地形因素对静止锋形成的影响:①我国西高东低的地势和东西走向的山系,迫使冬季西
The stationary front in Kunming is a special meteorological feature produced by the general circulation of the atmospheric circulation at a specific time (winter), a specific location (the eastern part of the Yunnan-Guizhou Plateau), and a specific terrain. In order to allow students to fully understand the principle of the formation of the static front, first of all, we know that the Yunnan-Guizhou Plateau is located at latitude 23°-30° N latitude on the south side of the westerly belt. In winter, the wind belts and pressure belts move southward and southward as the direct point of the sun moves. The second step is to understand the influence of topographic factors on the formation of the stationary front: 1 The low-lying and high-lying terrains of our country and the mountain system from east to west are forcing the winter to the west.
