一、太平洋的雾 1.概况 太平洋上的雾,分布在30°N以北和35°S以南洋面上,而中间的热带洋面上极少有海雾发生。 从北太平洋海雾分布来看,雾区集中于30°─50°N的洋面上,50°N以北除白令海峡夏季有雾之外,其他海域很少有雾。在这一带状雾区里,海雾的分布也是不均匀的,其中以大洋两侧海岸附近的海雾较多,而大洋中部却较少。北太平洋西岸,从千岛群岛南下到日本北海道一线,为北太平洋海雾最频繁的区域,而且雾的浓度也大。北太平洋东部加利福尼亚沿岸也是一个海雾区,虽然其频率和浓度与千岛群岛雾区相比较为逊色,然而在北太平洋东岸却是一个显著的海雾区。 海雾的分布有明显的季节变化,春、夏季分布范围广,出现频率高,且西部胜于东部;秋、冬季分布范围小,出现频率低,东部略高于西部。从冬季到夏季,海雾的分布范围逐渐由
I. Fog in the Pacific Ocean 1. General Fog over the Pacific Ocean is distributed over the ocean south of 30 ° N and 35 ° S with very few sea fog in the middle of the tropical ocean. According to the distribution of sea fog in the North Pacific Ocean, the fog area is concentrated on the ocean surface at 30 ° -50 ° N, and foggy in the rest of the sea except north of 50 ° N, except the summer fog in the Bering Strait. In this zonal fog zone, the distribution of sea fog is also uneven. Among them, there are more sea fog near the coast on both sides of the ocean and less in the middle of the ocean. The western North Pacific, from the Kuril Islands south to Hokkaido, Japan, is the most frequent area in the North Pacific Ocean, with a high concentration of fog. The California coast of the eastern North Pacific is also a maritime fog zone. Although its frequency and concentration are inferior to those of the Kuril Islands, it is a significant sea fog zone on the east coast of the North Pacific Ocean. The distribution of sea fog has obvious seasonal changes, with a wide distribution in spring and summer, high frequency of occurrence, and the western part is better than the eastern part. The autumn and winter distribution areas are small with low frequency and the eastern part is slightly higher than the western part. From winter to summer, the distribution of sea fog gradually by
