选用海洋调查船“实践”号、“向阳红09”号在全球大气试验热带风观测(TWOS)期间的六天观测资料及同期的两个岛屿站的探空记录,计算了区域平均的大尺度参数:相当位温、水平散度、相对涡度及垂直速度的垂直分布。结合热量,湿度的收支研究计算了视热源、视湿度汇及总涡动热通量的垂直分布,据卫星云图及海面气象观测将所研究的六天分为扰动控制及信风控制两类。通过扰动及信风控制下各大尺度参数平均值的比较,并与西太平洋赤道海域、大西洋信风区的其他研究结果相比较,得到西太平洋赤道槽区大尺度扰动结构上的一些特征。
Based on the six-day observation data during the global atmospheric test of tropical monsoon (TWOS) and the sounding records of two island stations in the same period, the ocean survey vessel “Practice” and “Xiangyang Hong 09” were selected to calculate the regional average large scale Parameters: Relative bit temperature, horizontal divergence, vertical distribution of relative eddy and vertical velocities. Based on the study of heat and humidity, the vertical distribution of apparent heat source, apparent moisture sink and total eddy heat flux was calculated. According to satellite image and sea surface meteorological observation, the studied six days were divided into two categories: disturbance control and letter control . The characteristics of large-scale disturbance structures in the equatorial Pacific region of the western Pacific are obtained by comparing the average values of the large-scale parameters under disturbance and letter-wind control with other studies in the equatorial Pacific Ocean and the Atlantic Ocean.
