| Abstract: | Analysis of spatial-temporal variation of precipitation in the upper reach of the Yellow River and its circulation characteristics are made. It shows that the bend region of the Yellow River is one of the area with richest precipitation in the upper reach of the Yellow River. The first ten days of July and the first ten days of September are the optimum periods of artificial precipitation enhancement over the bend region. |

| Keywords: | the upper reach of Yellow River spatial-temporal variation of precipitation circulation characteristics |
