| 摘 要： | 根据湖北地区2008年2月和2009年1月500 k V高压输电线实时观测资料,结合MICAPS常规气象资料和NCEP再分析资料,研究了湖北张恩高压输电线上电线积冰形成的天气形势和气象条件。结果表明:两次积冰过程中500 h Pa深厚的低压槽和850 h Pa低涡配合切变线靠近湖北促使积冰加重;气温和风速在两次积冰过程的形成阶段起到主要作用。

| Abstract: | Based on the real-time observation data on 500 kV high voltage transmission lines in Hubei area in February 2008 and January 2009,MICAPS conventional meteorological data and NCEP reanalysis data,this paper studies the synoptic systems and meteorological conditions during the two wire icing processes.Results show that the deep low pressure trough at 500 hPa and low vortex with shear line at 850 hPa,which is close to Hubei area,have positive effects on ice thickness during the two icing processes.The air temperature and wind velocity play a leading role in the initial stage of the two icing processes. |
