朝阳市2014年天气气候特征及对农业的影响分析

摘要

The temperature, rainfall and sunshine were analyzed based on the meteorological data in Chaoyang City in 2014. The results showed that annual average temperature was higher in Chaoyang City in 2014, and air tempera-ture varied over a much wider range. Phased low temperature in spring was obvious. The space-time distribution of less raifall was uneven and the summer drought was serious. The annual sun-shine hours were less in 2014. Summer drought, local rainstorm, mountain tor-rent, hailstone and other meteorological disasters brought greater loss for agricul-tural production and people's life and property.%利用朝阳市2014年气象资料，分析了气温、降水和日照变化情况。结果表明，2014年朝阳市年平均气温偏高，气温变化波动幅度较大，春季阶段性低温明显；年总降水量偏少且时空分布不均匀，夏季干旱严重；年日照总时数偏少。夏季干旱、局部暴雨、山洪、冰雹等气象灾害给农业生产和人民生命财产造成较大危害，经济损失较重。
