長江口和東海海域的氣象海況條件及安全航行對策

[摘要] 海洋環(huán)境的好壞直接影響到船舶的航行安全和經(jīng)濟(jì)效益，特別是某些惡劣的天氣系統(tǒng)所引起的狂風(fēng)巨浪和災(zāi)害性天氣不僅使船舶操縱困難，而且還可導(dǎo)致嚴(yán)重的海損事故，因此，對于各海域的氣象和海況，尤其是災(zāi)害性天氣的掌握就顯得尤為重要。本文主要探討研究了影響長江口和東海海域內(nèi)航行安全的氣象海況條件。結(jié)合長江口和東海特殊的地形地貌特征，總結(jié)長江口和東海海域的風(fēng)、浪、流等氣候要素的分布規(guī)律，以及在長江口和東海經(jīng)常出現(xiàn)的幾種重要的天氣系統(tǒng)。并在此基礎(chǔ)上系統(tǒng)分析了影響長江口和東海的災(zāi)害性天氣在各海區(qū)的分布規(guī)律。

The weather Conditions of the Yangtze River estuary and East China Sea and sea navigation safety countermeasures

Abstract：The ship's safety and economic effects depend on whether the oceanic conditions are good or not. Particularly some synoptic systems conducing the storm and very high sea not only makes the ships be manipulated difficultly, but also brings about fearful shipwreck. So, it looks particularly important to master the weather and sea condition of every sea area, in particular the disastrous weather. The paper focused on the weather and sea condition which impact the safety of navigation on The Yangtze River estuary and East China Sea. With special topography features of The Yangtze River estuary and East China Sea, the paper sum up the distribution of climate elements such as wind, wave and flow, and several important weather systems which often appear in The Yangtze River estuary and East China Sea, on basis of which, I systematically analyses the distribution of disastrous weather impacting The Yangtze River estuary and East China Sea in each sea area.
