发生暴风天气是正常现象，并且气温和降水超出正常范围也不足为奇，毕竟，人为划定“正常范围”终会造成这样的结果。
And it's not unusual for temperatures and precipitation levels to be higher or lower than normal. After all, that's how we end up with the artificial line called normal.
在美国，厄尔尼诺现象通常能为干旱的西南部带来有益的冬季降水，使北方的寒冷天气减弱，降低佛罗里达荒野火灾的风险。
In the US, it typically brings beneficial winter precipitation to the arid Southwest, less wintry weather across the North, and a reduced risk of Florida wildfires.
周二，农业部发布消息称，由于降水偏少，中国北部地区出现严重干旱现象，14000多万亩(930公顷)小麦受到影响。
Lack of rainfall has led to severe drought in northern China, affecting more than 140 million mu (9.3 million hectares) of wheat, said the Ministry of Agriculture (MOA) on Tuesday.
在干旱现象已经很常见的埃塞俄比亚，降水量又将在接下来的50年里下降10个百分点。
Rainfall in Ethiopia, where droughts are already common, could decline by 10 percent over the next 50 years.
成因：我国降水量的这种时间变化特征，是与季风因锋面移动产生的雨带推移现象分不开的。
Causes: My precipitation characteristics of this time, and because of the monsoon front moving with the rain goes inseparable from the phenomenon.
工程师们曾用各种经验性的方法依据降水的资料推演河槽裹水流的现象，以应各种工程建设对于水文分析的要求。
Engineers employed empirical methods to compute river discharges from precipitation data in answer to the ever-increasing demands made upon hydrologic analyses for engineering works.
最终，模式在整体系统误差上取得较大改进，对流层顶的温度场和风场误差明显减小，降水结构和降水强度显著改进，并且未见“双赤道辐合带”的现象。
Precipitation is dramatically improved both in the amount and the structure. Another advantage is that the false structure of "double Intertropical Convergence Zone (ITCZ)"is not seen in the result.
