摘要

分析了2008

009年湖南地区冬季的整体天气形势

利用覆冰监测预警系统的监测数据

发现2008

009年冬季电网覆冰为中等以下强度的覆冰。将电网覆冰长期预测、中期预测和短期预测结果与电网实际覆冰情况进行对比

发现电网长期预测结论与实际情况十分吻合

中期预测也有较高准确性

短期预测准确率达99%以上。针对下一步的工作给出了建议。

Abstract

The whole weather condition of 2008

009 winter in Hunan was analyzed.According data from icing monitoring and alarming system

it is found that the ice-covering condition in 2008

009 winter was less severer than medium intensity.Compared the actual ice-covering condition with long term

medium-term

and short term forecasts

it was found that long term and medium term forecast accuracy is suitable and short-term forecast accuracy is more than 99%.Suggestions were proposed for next work stage.
