摘要

The RAMS model was run for the period 5 -13 January 1987. The SLAM-P model then used the RAMS data to simulate the 3 -hour releases on 5 January (1700 -2000 UTC) from St. Cloud. During the first sampling day (1400 UTC 5 January to 1400 UTC 6 January) the observed plume went north -northwest into northern Minnesota. During the second plume day (1400 UTC 6 January to 1400 UTC 7 January) the plume shifted to the south into Nebraska, Kansas and Missouri in response to the development of a low -pressure system over the central plains. During this time, the predicted plume from SLAM-P matched the observed plume (see Table 1) over Kansas and Nebraska very well but was a little slow over southern Missouri. During the third plume day (1400 UTC 7 January to 1400 UTC 8 January) the observed plume continued moving south down into Oklahoma and Arkansas. As shown in table 2, the predicted plume from SLAM -P was within a factor of 2 or 3 of the observed plume. More results will be presented at the conference.
