简介:最近报导的结果显示起始的错误很快并且随后种的那个小振幅和小规模污染短期的确定的中央规模预报。这快速的错误生长依赖于不仅潮湿的传送对流而且流动政体。在这研究,中央规模可预测性和mei-yu的错误生长,重降雨被在东方中国在42003年7月6日上沿着mei-yu前面模仿一个特别降水事件调查。由于mei-yu前面和规模相互作用的多尺度的特性,重降雨预报的mei-yu的错误生长在中间纬度的潮湿的baroclinic系统与那显著地不同。错误的最佳的生长有一个相对宽的系列,尽管它逐渐地从小规模与时间移居到中央规模。在这个重降雨事件的整个句号期间,错误生长有三个不同阶段,它类似于6小时的积累的降水的进化。多步错误生长作为错误,错误的水平规模,或两个的振幅的增加表明。在发展的预报错误的垂直侧面对流系统显示二座山峰,它与对流不稳定性和潮湿的物理相应。为mei-yu的错误生长重降雨在mei-yu前面内被集中,并且与潮湿的对流不稳定性和规模相互作用有关。
