中文摘要:
      Bergeron定义在42.5°纬度气旋加深率达到19hPa 24h-1者为"气象炸弹"。东亚海岸气旋的发展经常可以超过这个标准。这种爆发性发展前高空温压场的特征和中等程度的发展相似。因此,"气象炸弹"的产生应该是斜压过程和其他机理的综合结果[1]
英文摘要:
      A series of numerical experiments for a case of East Asia coastal cyclogenesis were carried out by using ECMWF grid point limited area model.The results show that the decreasing of the surface friction over the ocean is essential for the cyclone development and the mechanical forcing of the Qinghai,Tibet Plateau acts as a damping effect in the initial stage of the cyclone,
