在广东省编的中学复习丛书——《地理》中,有一道思考题:“信风带地区降水多还是西风带地区降水多?为什么?”这道题,提得好,富有思考价值。但如何才是正确的答案呢?这就需要从各有关方面分析阐明。我们不妨将地球上降水量按纬度分布情况概括为下面图表(注),然后进行分析。图表中表明:就多年平均状况来说,降水是由赤道向两极趋于减少;赤道低气压带和信
In the series of secondary school review books compiled by the Guangdong Province, “geography”, there is a question: “Does the precipitation in the area of the letter-wind belt is more precipitation in the westerly belt? Why is this?” This question is well-founded and worth thinking. . However, what is the correct answer? This requires analysis and clarification from various parties. We may sum up the latitude distribution of precipitation on the earth as the following chart (Note), and then analyze it. The chart shows that, in terms of the average annual situation, the precipitation tends to decrease from the equator to the poles; the equatorial low pressure zone and the letter
