【摘要】 研究了 3月中旬～ 5月上旬浙江省双季早稻育秧期长、中、短连阴雨的时空分布规律 ,以及年代间演变规律。研究发现 :3月中旬～ 5月上旬 ,全省连阴雨总的趋势为自北向南增加 ;在同纬度地区 ,内陆出现频率大于沿海 ;浙中南地区所受连阴雨影响大于浙北地区 ;90年代长连阴雨出现频率增加。连阴雨是浙江省早稻育秧期间的主要农业气象灾害之一。更多还原

【Abstract】 This article analyzed the spatial-temporal distribution and interanual course of cloudy-rainy weather for several days with different time scales from the second ten-day in March to the first ten-day in May when the double cropping early rice is in the seeding and seedling-raising stage. The study shows that: (1) Cloudy-rainy weather for several days in Zhejiang tends to increase from North to South. (2) At the same latitude, its appearance in the inland regions is more frequent than in the coastal ones. (3) The damage in Central and South Zhejiang is more serious than North Zhejiang. (4) The frequency of it increased in the 90s. Cloudy-rainy weather for several days is one of the major agrometeorological disaster during the seeding and seedlings-raising stage of the double cropping of early rice in Zhejiang Province.更多还原
