Figure 1 is a 1 km resolution image of the Yangtze River Basin taken by the NOAA-14 Polar-orbiting Operational Environmental Satellite (POES) on August 14, 1998. The numbers annotated on the image are correlated to precipitation totals for the June-July 1998 (see Table 1) period in descending order. All stations are in southeast China (WMO Blocks 53, 54, 57, 58, and 59). The satellite image does not include other areas where flooding has been a major problem; specifically, around the Gulf of Tonkin in the south, and in the Manchuria area across the north. Additional data are available in Tables 2, 3 and 4, which list rainfall data for southeast China during June 1998, July 1998, and the June-July 1998 period, respectively. Table 5 (2 mb file) provides the daily data for these stations for June-July (click here for format documentation, and here for a station ID list). |

Figure 2 is a graph of the daily precipitation recorded at Qinzhou, near the Gulf of Tonkin, for June-July 1998. The precipitation plot shows several extreme rainfall episodes during the two-month period. For example, the greatest June event occurred over a three-day period with a total of over 12.00 inches, and the greatest one-day amount was over 9.00 inches. In July, there was an eight-day stretch of rain between the 2nd and the 9th when 29.18 inches of rain was recorded. Two tropical systems, Nichole and 01W, affected the extreme southern part of China during the month of July and contributed to the extraordinary rainfall amounts.
Figure 3 is another plot of daily precipitation for the city with the most precipitation in the Yangtze River basin, Jingdezhen, which reported 51.25 inches of precipitation. This station had a one-day total over 9.00 inches in June 1998; in July 1998, there was a ten-day period between the 17th and the 26th when 16.07 inches of rain was recorded.

Extreme Precipitation TableTop 30 stations' rainfall amounts in southeast China for June-July 1998, in inches and hundredths. 'Days' indicates number of days with rainfall data for the 2 months. Lat/lon are in degrees and minutes; 'elev' is the elevation in meters. Ranking by rainfall amount (1-30) follows station name; stations with an * indicate they are not plotted in Figure 1 since they're outside the map area.
