【摘要】 应用云南蒙自探空站2001-2004年的高空风、特性层资料分析了滇东南上空冬、春季到热带急流的时空分布特点及其对大气层结的影响,结合蒙自711数字化雷达站在其春季(3-4月)中观测刭的强冰雹云回波进行分析。结果表明,春季高空副热带急流是造成滇东南地区大气不稳定层结的重要因子之一,天气系统触发不稳定大气层结产生强冰雹云,副热带急流具有加强、维持发展的作用。更多还原

【Abstract】 Apply the high sky wind, the characteristic layer data of 2001-2004 years of Yunnan Mengzi, Analyzing the high strong wind of southeast winter, spring in Yunnan distributes the characteristics, Strong hail cloud prognosticate in the spring (3-4 months) of applied weather radar returns to wave to carry on the analysis. The result enunciation: In spring high sky strong wind is result in southeast region in Yunnan of one of the important factors of the unsteady layer knot of atmosphere, the weather system trigger the unsteady atmosphere knot to produce strong hail cloud, the high strong wind have to strengthen, the function of the maintenance development.更多还原
