日照沿海海陆风的气候特点及其对天气的影响

使用近海海温资料和莒县站、日照站气象资料，用对比分析的方法分析了日照地区沿海海陆风的气候特征及对当地天气的影响。发现海陆风明显的季节变化和日变化对当地气温、降水、湿度及天空状况等气象要素的空间和时间分布影响显著。海风强盛季节的午后和陆风强盛季节的早上，沿海的温度梯度常具有海风锋和海岸锋的特征，使沿海地区低云和雷暴天气明显增多，降水分布具有明显的海陆风和地形影响特征。

Climatic Characters of Land and Sea Breeze and It's Influence on Weather in Rizhao

The climatic charactors of Land and Sea breeze and it's influence on the local weather in Rizhao are analyzed by using the data of Juxian, Rizhao meteorological stations and the data of sea temperature. The results show that the variation of daily and seasonal land and sea breeze obviously affects the spatial and temporal distribution of the local temperature, precipitation, moisture, and cloud condition. The gradient wind often shows the fectures of sea breeze front and zonal coast front in the afternoon during stronger sea breeze and in the early morning during stronger land breeze. Low cloud and thunderstorm weather phenomena obvously increase,and the land and sea breeze and terrain obviously affect the precipitation distribution.
