Formation and Development of a Mountain-induced Secondary Center inside Typhoon Morakot(2009)

The structural evolution of Typhoon Morakot(2009) during its passage across Taiwan was investigated with the WRF model. When Morakot approached eastern Taiwan, the low-level center was gradually filled by the Central Mountain Range(CMR), while the outer wind had flowed around the northern tip of the CMR and met the southwesterly monsoon to result in a strong confluent flow over the southern Taiwan Strait. When the confluent flow was blocked by the southern CMR, a secondary center(SC) without a warm core formed over southwestern Taiwan. During the northward movement of the SC along the west slope of the CMR, the warm air produced within the wake flow over the northwestern CMR was continuously advected into the SC, contributing to the generation of a warm core inside the SC. Consequently, a well-defined SC with a warm core, closed circulation and almost symmetric structure was produced over central western Taiwan, and then it coupled with Morakot's mid-level center after crossing the CMR to reestablish a new and vertically stacked typhoon. Therefore, the SC inside Morakot was initially generated by a dynamic interaction among the TC's cyclonic wind, southwesterly wind and orographic effects of the CMR, while the thermodynamic process associated with the downslope adiabatic warming effect documented by previous studies supported its development to be a well-defined SC. In summary, the evolution of the SC in this study is not in contradiction with previous studies, but just a complement, especially in the initial formation stage.

The Forced Secondary Circulation of the Mei-yu Front

Using National Centers for Environmental Prediction reanalysis data for the period 28 June to 12 July during 2001 to2013, the secondary circulation(SC) associated with the mei-yu front was quantitatively diagnosed by numerically solving a primitive version of the Sawyer-Eliassen equation. Results demonstrate that a direct SC exists near the mei-yu front zone during mid-summer and the synoptic-scale geostrophic deformations are the main factors determining SC structures. About94% of the sinking s...     

Secondary flows in the lee of porous shelterbelts

The results of wind-tunnel experiments indicate that the flow close to the surface behind shelterbelts is quite sensitive to the orientation of the barrier to the mean flow direction, and that orientation is more important for short than long windbreaks. The implications of these findings are discussed in the context of field experiments to validate mathematical models of shelter effects.     

Anthropogenic Effects on Biogenic Secondary Organic Aerosol Formation

Anthropogenic emissions alter biogenic secondary organic aerosol(SOA) formation from naturally emitted volatile organic compounds(BVOCs). We review the major laboratory and field findings with regard to effects of anthropogenic pollutants(NOx, anthropogenic aerosols, SO_2, NH_3) on biogenic SOA formation. NOx participate in BVOC oxidation through changing the radical chemistry and oxidation capacity, leading to a complex SOA composition and yield sensitivity towards NOx level for different or even specific hydrocarbon precursors. Anthropogenic aerosols act as an important intermedium for gas–particle partitioning and particle-phase reactions, processes of which are influenced by the particle phase state, acidity, water content and thus associated with biogenic SOA mass accumulation. SO_2 modifies biogenic SOA formation mainly through sulfuric acid formation and accompanies new particle formation and acid-catalyzed heterogeneous reactions. Some new SO_2-involved mechanisms for organosulfate formation have also been proposed.NH_3/amines, as the most prevalent base species in the atmosphere, influence biogenic SOA composition and modify the optical properties of SOA. The response of SOA formation behavior to these anthropogenic pollutants varies among different BVOCs precursors. Investigations on anthropogenic–biogenic interactions in some areas of China that are simultaneously influenced by anthropogenic and biogenic emissions are summarized. Based on this review, some recommendations are made for a more accurate assessment of controllable biogenic SOA formation and its contribution to the total SOA budget. This study also highlights the importance of controlling anthropogenic pollutant emissions with effective pollutant mitigation policies to reduce regional and global biogenic SOA formation.     

包含超梯度力作用的台风次级环流诊断方程

次级环流在台风的发展和维持中起着重要作用,基于梯度风平衡的Sawyer Eliassen（SE）方程常用于台风次级环流的诊断。然而梯度风平衡关系在台风边界层及边界附近有较大误差,这导致SE方程求解出的次级环流在边界层也会有较大误差。本文在梯度风平衡方程中保留包含径向摩擦力项在内的超梯度力项,得到包含超梯度力作用的SE方程,从方程形式上看超梯度力主要是通过调节与斜压性相关的系数来影响次级环流的。对“森拉克”（2008）台风次级环流的诊断结果显示,在不人为改变边界层流场结构的情况下,新的SE方程能显著改善次级环流的求解效果,避免眼墙外侧边界层附近的虚假对流并且减小虚假入流。
