昨天“出梅”，今天“入伏”。<br>
<br>
<br>
何谓“出梅”？何谓“入伏”呢？现在来讲讲。<br>
<br>
<br>
每年阳历的6月中旬左右，在长江中下游一带的上空，来自太平洋暖湿气流与来自西伯利亚的冷空气会合于此，在空中形成“锋面”，这锋面长不过几百或几十公里，但宽却有几千公里，锋面在长江中下游一带摆动，形成三晴两雨的天气状况，由于这段时间恰是梅子（即杏）成熟的季节，而梅子的成熟，也就喜这三晴两雨的天气，故而古来称此为”梅“雨。过去少楼房，因连绵的阴雨，常使家中的衣物用具发霉，所以又称“霉”雨。<br>
<br>
<br>
冷暖气流会合而形成的锋面雨，在我国的雨水中约占百分之九十多，也就是说我国的雨水大多是锋面雨。<br>
<br>
<br>
随着地球神奇的自转功能，北半球的温度越来越高，太平洋的暖湿气流也越来越强大，进入七月中旬，强大的暖湿气流将冷空气一直往北推去，这时，长江中下游一带的梅雨季节宣告结束，进入伏天。<br>
<br>
<br>
而北方，则因暖湿的气流带来丰沛的雨水，开始了高温、多雨的气候，这也是为何我国东北的高纬度地区却仍能收获一季水稻的原因。而此时的长江中下游地区，将迎来高温、伏旱、少雨的到来。<br>
<br>
<br>
这一“出”与一“进”，夏季的酷热，真正来临了。<br>
