摘要

摘要: 海表风速、有效波高的长期变化趋势与全球气候变化、防灾减灾、海洋能开发等密切相关。本文利用CCMP风场驱动WW3海浪模式,模拟得到近24年(1988-2011年)的中国近海海浪场数据。利用CCMP风场、模拟海浪数据,分析了中国海域海表风速、有效波高长期变化趋势的季节特征。结果表明:(1)在近24年期间,中国海的海表风速、有效波高都表现出显著性逐年递增,趋势分别为:3.38 cm/(s·a)、1.3 cm/a。(2)整体来看,海表风速、有效波高在春季、冬季的递增趋势最强,夏季次之,秋季的递增趋势相对最弱。(3)春季,海表风速呈递增趋势的范围为全年最广,夏季和冬季呈递增的范围有所缩小,秋季呈递增的范围为全年最小。与海表风速不同,在春季和冬季,整个中国海范围的有效波高都表现出显著的递增趋势,夏季和秋季呈递增的范围有所缩小。渤海、黄海、东海、对马海峡、台湾海峡、南海北部海域、北部湾、泰国湾的海表风速、有效波高在各个季节都表现出显著的递增趋势。(4)在不同海域,海表风速、有效波高的变化趋势由不同季节主导。呈强劲递增趋势的海域,海表风速和有效波高的变化趋势通常由冬季主导。

Abstract: Long-term variations in a sea surface wind speed (WS) and a significant wave height (SWH) are associated with the global climate change, the prevention and mitigation of natural disasters, and an ocean resource exploitation, and other activities. The seasonal characteristics of the long-term trends in China's seas WS and SWH are determined based on 24 a (1988-2011) cross-calibrated, multi-platform (CCMP) wind data and 24 a hindcast wave data obtained with the WAVEWATCH-Ⅲ (WW3) wave model forced by CCMP wind data. The results show the following. (1) For the past 24 a, the China's WS and SWH exhibit a significant increasing trend as a whole, of 3.38 cm/(s·a) in the WS, 1.3 cm/a in the SWH. (2) As a whole, the increasing trend of the China's seas WS and SWH is strongest in March-April-May (MAM) and December-January-February (DJF), followed by June-July-August (JJA), and smallest in September-October-November (SON). (3) The areal extent of significant increases in the WS was largest in MAM, while the area decreased in JJA and DJF; the smallest area was apparent in SON. In contrast to the WS, almost all of China's seas exhibited a significant increase in SWH in MAM and DJF; the range was slightly smaller in JJA and SON. The WS and SWH in the Bohai Sea, the Yellow Sea, East China Sea, the Tsushima Strait, the Taiwan Strait, the northern South China Sea, the Beibu Gulf, and the Gulf of Thailand exhibited a significant increase in all seasons. (4) The variations in China's seas SWH and WS depended on the season. The areas with a strong increase usually appeared in DJF.
