参考答案

正确答案：B
解析：从第三段的内容...wintertime rainfall in the northern mid to high latitudes and Antarctica will rise, that meanwhile Australia, Central America and southern Africa are likely to see decreases in autumn precipitation, that some land areas in the tropics will see more rainfall,...来看，所谈论的是不同地区、不同时节的降雨量。因而，可推断 precipitation为“降水，降水量”。rainfall降雨，降雨量；latitude纬度，范围；projection发射，计划，设计。
