求翻译：在秋季和春季主要城市周围的降水量变化都比较小，而且三个实验的结果都是降水量减少，地面升温对降水分布特征没有明显的影响是什么意思？

In major cities around the fall and spring precipitation changes are relatively small, and the results of three experiments is less precipitation, surface temperature had no significant effect on precipitation distribution characteristics

In the fall and spring around the major cities of precipitation changes are relatively small, and 3 of the results of the experiments are less precipitation, surface warming on precipitation distribution characteristics there is no obvious impact

Quite is all small around the autumn and the spring main city precipitation change, moreover three experimental results all are the precipitation reduce, the ground elevates temperature to the precipitation distributes the characteristic not obvious influence

In the autumn and spring precipitation around the major cities are quite small, and three experimental results are reduction of precipitation, surface warming on precipitation distribution does not have a significant impact
