| 1 | 中国海雾研究简要回顾显示文摘海雾是指对海上船舶航行、捕捞、港口作业以及沿海地区的公路运输和电力输送等社会生活的方方面面产生重要影响的天气现象。有研究指出,由于雾所造成的社会经济和人力资源的损失甚至与台风和龙卷风造成的损失相当。因此对近30a来我国海雾研究领域的重要进展进行了回顾,并对海雾的微物理学特征、海雾与层云的关系、北太平洋与大西洋上海雾发生频率的气候学特征、海雾的数值模拟、海雾的数据同化和集合预报等重要问题进行了讨论。 | 傅刚 李鹏远 张苏平 高山红 | 2016 | 气象科技进展2016,6,2: | 25 |
| 2 | 2016年春季一次黄渤海明显海雾过程的大气海洋特征分析显示文摘利用FY卫星资料、自动气象站逐小时观测资料、ERA 0.5°×0.5°再分析资料对2016年3月3—5日黄渤海明显海雾过程形成机制进行了分析,结果发现:逆温层、低层上升中层下沉的配置提供了有利的层结条件;水汽条件源于黄海输送,南到东南风将暖湿空气向北输送,然后在偏东风作用下输送入渤海;降温条件源于海气界面湍流热交换,大气向海洋输送的湍流热通量使得湿空气降温凝结,达到饱和形成海雾。 | 史得道 黄彬 吴振玲 | 2018 | 海洋预报2018,35,5: | 10 |
| 3 | 2015-04-28渤海海雾形成过程中的海气相互作用分析显示文摘利用FY和MTSAT卫星资料、ERA Interim再分析资料、黄渤海浮标站资料、黄渤海自动站逐小时观测资料,对发生在2015年4月28—29日的渤海海雾成因进行分析,着重探讨了海雾形成过程中的海气相互作用。结果发现,近海面处大气低层逆温层抬升,大于90%的大湿度区向上、向西扩展,对海雾形成非常有利;海雾生成前、生成发展过程中存在明显的东到东南风,有利于黄海水汽向渤海输送,海面上空有水汽通量大值区由渤海海峡向渤海中部移动,使得渤海上空水汽输送加强,提供了海雾形成所需的水汽;在海雾形成过程中渤海上空气温高于海温,风切变造成的海气界面湍流热交换为大气输送向海洋,使得冷海面上空暖湿空气降温冷却达到饱和形成海雾,是平流冷却雾。 | 史得道 吴振玲 罗凯 左涛 | 2018 | 热带气象学报2018,34,3: | 9 |
| 4 | The Structure and Formation Mechanism of a Sea Fog Event over the Yellow Sea显示文摘In this paper, a heavy sea fog event occurring over the Yellow Sea on 11 April 2004 was investigated based upon observational and modeling analyses. From the observational analyses, this sea fog event is a typical advection cooling case. Sea surface temperature(SST) and specific humidity(SH) show strong gradients from south to north, in which warm water is located in the south and consequently, moisture is larger in the south than in the north due to evaporation processes. After fog formation, evaporation process provides more moisture into the air and further contributes to fog evolution. The sea fog event was reproduced by the Regional Atmospheric Modeling System(RAMS) reasonably. The roles of important physical processes such as radiation, turbulence as well as atmospheric stratification in sea fog's structure and its formation mechanisms were analyzed using the model results. The roles of long wave radiation cooling, turbulence as well as atmospheric stratification were analyzed based on the modeling results. It is found that the long wave radiative cooling at the fog top plays an important role in cooling down the fog layer through turbulence mixing. The fog top cooling can overpower warming from the surface. Sea fog develops upward with the aid of turbulence. The buoyancy term, i.e., the unstable layer, contributes to the generation of TKE in the fog region. However, the temperature inversion layer prevents fog from growing upward. | GUO Jingtian LI Pengyuan FU Gang ZHANG Wei GAO Shanhong ZHANG Suping | 2015 | Journal of Ocean University of China2015,14,1: | 4 |
| 5 | Impact of the Pacific–Japan Teleconnection Pattern on July Sea Fog over the Northwestern Pacific: Interannual Variations and Global Warming Effect显示文摘The northwestern Pacific(NWP) is a fog-prone area, especially the ocean east of the Kuril Islands. The present study analyzes how the Pacific–Japan(PJ) teleconnection pattern influences July sea fog in the fog-prone area using independent datasets. The covariation between the PJ index and sea fog frequency(SFF) index in July indicates a close correlation, with a coefficient of 0.62 exceeding the 99% confidence level. Composite analysis based on the PJ index, a case study, and model analysis based on GFDL-ESM2 M, show that in high PJ index years the convection over the east of the Philippines strengthens and then triggers a Rossby wave, which propagates northward to maintain an anticyclonic anomaly in the midlatitudes,indicating a northeastward shift of the NWP subtropical high. The anticyclonic anomaly facilitates the formation of relatively stable atmospheric stratification or even an inversion layer in the lower level of the troposphere, and strengthens the horizontal southerly moisture transportation from the tropical–subtropical oceans to the fog-prone area. On the other hand, a greater meridional SST gradient over the cold flank of the Kuroshio Extension, due to ocean downwelling, is produced by the anticyclonic wind stress anomaly. Both of these two aspects are favorable for the warm and humid air to cool, condense, and form fog droplets, when air masses cross the SST front. The opposite circumstances occur in low PJ index years, which are not conducive to the formation of sea fog. Finally, a multi-model ensemble mean projection reveals a prominent downward trend of the PJ index after the 2030 s, implying a possible decline of the SFF in this period. | Jingchao LONG Suping ZHANG Yang CHEN Jingwu LIU Geng HAN | 2016 | Advances in Atmospheric Sciences2016,33,4: | 1 |
| 6 | Advancing Climate Dynamics Toward Reliable Regional Climate Projections显示文摘With a scientific consensus reached regarding the anthropogenic effect on global mean temperature, developing reliable regional climate projections has emerged as a new challenge for climate science. A national project was launched in China in 2012 to study ocean's role in regional climate change. This paper starts with a review of recent advances in the study of regional climate re-sponse to global warming, followed by a description of the Chinese project including the rationale, objectives, and plan for field ob-servations. The 15 research articles that follow in the special issue are highlighted, representing some of the initial results from the project. | XIE Shang-Ping | 2013 | Journal of Ocean University of China2013,12,2: | 1 |
| 7 | 春季东海黑潮锋影响强对流的个例分析显示文摘利用卫星观测和再分析资料,研究了2018年4月30日东海黑潮海面温度锋(黑潮锋)影响低云突破边界层发展为对流云团,并导致强降水的过程。结果表明:(1)29日12时东海500 hPa上受短波槽控制,低空处于高低压之间的偏南气流中;黑潮锋大气边界层稳定,有利于低云发展。(2)黑潮锋的暖水侧向大气不断输送热量和水汽,稳定性减弱;而冷水侧对大气的冷却作用显著,大气稳定性增加。(3)经过约12 h的调整,黑潮锋通过垂直混合机制强迫表层风速发生变化,在黑潮锋上空形成风速辐合,叠加背景辐合场,导致辐合明显增强。(4)受平流效应影响,黑潮锋上空大气增湿增温,抬升凝结高度降低。(5)潜热释放与低空辐合之间形成正反馈,最终导致对流云团发展,降水强度显著增强。 | 周解梦 张苏平 张银意 | 2022 | 海洋气象学报2022,42,2: | 0 |
| 8 | 近18 a山东半岛南部海域海面温度的长期变化研究显示文摘为探讨山东半岛南部海域海面温度的长期变化,本文利用当前国际上水平分辨率较高的多卫星观测融合数据对2003—2020年间的海面温度进行了分析研究。结果表明:(1)除威海和连云港部分近岸海域外,山东半岛南部大部分海域的海面温度显著升高,升温速率最大值可达0.083℃/a。海面增温存在显著的季节变化,主要出现在春末至秋初(4—9月),且近岸海域强于外海。(2)除青岛外海外,大部分海域的暖季开始日提前,暖季持续时间延长,其中在海州湾和烟台、威海近岸及南部海域最为显著;年最高温度升高,在连云港近海和海州湾、胶州湾等海域较为显著,但其发生日并无显著提前或者延后。(3)冬半年,山东半岛南部近岸海域和部分外海海域有较强的温度锋面,并在过去18年间显著增强。(4)海面温度在冬季的年代际变化与太平洋年代际振荡(PDO)相关性较好,但在其他季节与PDO的相关性较弱。 | 陆雪 刘子洲 翟方国 | 2023 | 海洋科学2023,47,4: | 0 |
| 9 | 2015-2020年渤海西海岸雾的海陆分布差异成因分析显示文摘利用2015—2020年渤海西海岸陆地和近海加密自动站、再分析资料和卫星反演雾资料,分析该地区海陆雾时空分布特征,选择一次典型个例开展敏感性数值实验。结果表明:渤海西海岸秋季、冬季陆雾多于海雾,而春季、夏季相反,虽然冬季海雾和陆雾数量最多且变化趋势一致,但分布仍具有显著的局地性;渤海西海岸雾以海岸线为界的频率大于53%,多出现在夜间,持续时间也多低于12 h。个例分析表明,海陆风环流将海上暖湿空气输送至内陆低空,湿度快速增大至近饱和,弱冷空气入侵和夜间长波辐射降温共同作用,导致内陆大雾形成。而海温较高、海洋大气降温缓慢,难以形成海雾;海温敏感试验结果也表明,海温增加5%后,控制实验中略微进入近海的雾区基本回退到海岸线以西,海温降低5%后,陆雾蔓延至整个渤海并维持,高海温是本次陆雾未扩展入海的关键因素。 | 靳振华 吴彬贵 廖云琛 龙强 卜清军 | 2023 | 气象与环境学报2023,39,4: | 0 |
