TOGA: Air-Sea Exchange Processes in TOGA COARE

这项研究是利用在密集观测期间进行的飞机测量来研究托加COARE区域(西太平洋暖池)的海气相互作用过程。将使用配备湍流的飞机确定海-气通量、它们的可变性、参数化及与海洋和大气的耦合。提出了几种独特的飞行计划，在高度协调的飞行模式中使用2架或3架飞机来测量通量的地表变率、边界层的垂直结构以及大气感热、水汽和动量收支。以TOGA COARE船和浮标为中心的图案强调了与海洋的耦合。如有可能，将在较大的雷达阵列和岛屿探测站的范围内确定大气预算。飞机感热、水汽和动量边界层预算将与从舰船和雷达阵列估计的更大规模的预算进行比较，以确定更大规模预算的统计基础。这项研究很重要，因为它是TOGA COARE研究之一，它考察了世界上一个特别气候敏感的区域--西太平洋暖池系统--TOGA COARE现场的海洋和大气耦合的主要过程。

This research is a study of air-sea interaction processes in the TOGA COARE region (western Pacific warm pool) using aircraft measurements taken during the Intensive Observing Period. Air-sea fluxes, their variability, parameterizations and coupling to the ocean and atmosphere will be determined using turbulence-equipped aircraft. Several unique flight plans are proposed which use 2 or 3 of the aircraft in highly-coordinated flight patterns to measure the surface variability of the fluxes, the vertical structure of the boundary layer and the atmospheric sensible heat, moisture, and momentum budgets. The coupling to the ocean is emphasized with the patterns centered over the TOGA COARE ships and buoys. The atmospheric budgets will be determined when possible within the scale of the larger array of radars and island sounding stations. The aircraft sensible heat, moisture, and momentum boundary-layer budgets will be compared to the larger scale budgets estimated from the array of ships and radars to determine the statistical basis of the larger scale budgets. This research is important because it is one of the TOGA COARE studies that examines the principal processes responsible for the coupling of the ocean and the atmosphere in an especially climate sensitive region of the world, the western Pacific warm pool system, the field site of TOGA COARE.
