Abstract: |
in this paper, using micaps ground meteorological observation data, the guidance of the national meteorological center forecast, WRF numerical forecast products, the United States three temperature prediction data, automatic station of live, the lowest temperature in November 2017 in huludao region according to the weather system is analyzed after parting, the results show that the low voltage control type weather, suizhong low temperature is lower than the mountains, low temperature forecast according to the rules of SCMOC and WRF"s temperature forecast for correction; The high pressure front type weather, suizhong low temperature is higher than lianshan, and the low temperature of xincheng is lower than jianchang, the low temperature forecast can be revised according to the law to WRF and the American temperature forecast; The high pressure control weather can be revised according to the previous day"s forecast of WRF and the United States. High pressure top type weather can be revised according to the law. |
