利用辽宁省常规气象观测站气温资料,1981—2010年美国环境预报中心(NCEP)500h Pa高度场、850 h Pa温度场、地面气压资料,依据辽宁省水稻各生长期低温冷害指标,从农作物秧苗期到分蘖成熟期,分析不同阶段低温冷害分布特征和致灾的天气学成因,总结低温冷害预报规律。
【英文摘要】
Used the temperature datas of automatic weather stations and NCEP 500 h Pa height field and 850 h Pa temperature field and surface pressure data from 1981 to 2010 to analyze the distribution characteristics and its meteorological factors leading to disaster at different stages of rice growing on the basis of growth indicators of rice.At the end,summarized the law of forecasting the rice chilling damages.
