2013年12月15~17日广东出现了一次区域性的暴雨过程,这次暴雨过程范围广、持续时间长在冬季极其罕见.河源地区普降暴雨,15日到16日(08时至08时雨量)河源全市93个有记录的自动站中共出现119站日次暴雨.河源过程雨量主要集中在中部和西部,15日02时至17日08时河源过程累积降水雨量为47.7mm到192.0mm,过程最大雨量出现在东源漳溪为192.0mm.本文利用常规观测资料、区域加密气象站观测资料、NCEP/NCAR的1 °×1 °全球同化数据系统分析资料,采用天气学分析和动力诊断,试图通过分析本次暴雨的天气系统及其与常态的差异,重点分析南支槽性质、静止锋变化及其水汽、动力和热力等条件揭示这次河源冬季暴雨发生的成因,以期对河源地区冬季暴雨的预报分析有一定的帮助.

地球上存在着一种或两种达到或超过人类生命耐受范围的极端环境(如高盐、强碱或强酸、高温或低温环境等).但是,地球上还存在着一些更极为复杂的多极端环境.如一些内陆盐碱湖由于地表土壤含大量的碳酸盐及气候干旱等原因,经过上万年的不断演化,使得湖水及其近岸土壤中含有高浓度的盐离子和强碱性pH(以碳酸盐含量高),并且太阳的暴晒使表层温度很高.因此,生存于这些多极端环境的微生物需要不断进化以适应更为复杂的极端条
