This dataset is the wind driven component of transport in the surface boundary is directed perpendicular to wind stress. Negative wind stress curl indicates the winds are placing a clockwise spin on the ocean surface whereas positive wind stress curl indicates the winds are placing a anti-clockwise spin on the ocean surface. (The curl of a field of vectors is a vector which measures the tendency of the vectors to induce rotation.). Wind curl is calculated for the 23 year period from 1976 to 1998 inclusive. Calculated from NCEP Reanalysis data provided by the NOAA-CIRES Climate Diagnostics Center, Boulder, Colorado, USA, from their Web site at http://www.cdc.noaa.gov/
本数据集聚焦地表边界层中风驱动的输运分量，该分量的方向与风应力（wind stress）相垂直。负风应力旋度（wind stress curl）代表风对海洋表层施加顺时针旋转作用，正风应力旋度则代表风对海洋表层施加逆时针旋转作用。（矢量场的旋度（curl）是用于衡量矢量诱导旋转趋势的矢量。）本数据集的风旋度计算时段为1976年至1998年（包含首尾年份），共计23年。数据源自美国科罗拉多州博尔德市NOAA-CIRES气候诊断中心提供的NCEP再分析（NCEP Reanalysis）数据，其官方网站为http://www.cdc.noaa.gov/
