| 摘要: |
| 利用TOGA-COARE强化期(IOP)"实验3"号科学考察船所取得的表面气象和探空资料,对考察期间的热通量进行详尽的分析和计算,特别是对发生在IOP期间的两次西风爆发过程中西太平洋热带海域热通量的特征进行了重点分析,并讨论了它们与大尺度环流及其中高纬度环流的关系。结果表明:与其它天气过程相比,在西风爆发过程中,海洋向大气输送的感热和潜热最大,其形成原因与北半球的越赤道气流有重要关系。不同的天气过程热量输送也不同。 |

| Abstract: |
| based on the surface meteorological and radiosonde data during the IOP of TOGA-COARE at observation station (2°15′S,158°E)of "R/V Shiyan3",the heat flux during IOP is exhaustively analysed,especially for the heat flux of two WWBs(westerly wind bursts) over the tropical western Paciffic during IOP.Meanwhile,the relationships among large-scale circulation middle and high latitude circulation have been discussed.The results show that the latent and sensible heat fluxes over the tropical western Pacific,which have been transported from sea surface into air,are maximum in both WWBs,their causes of formation have important relations with the cross-equatorial flow from winter hemisphere,and the transportation of heat is differient under different weather conditions. |
