The goal of the Seasonal Equatorial Atlantic Experiment (SEQUAL) was to explain the response of the Equatorial Atlantic ocean to the forcing winds. A set of models was developed and a very complete set of data (winds, currents, temperature) was obtained in 1983-1984. The purpose of this proposal is to study the propagation and growth of errors in a dynamical model of the Equatorial Atlantic from initial conditions set by observations and subsequent data assimilation olf new observations in space and time. This is an important task for the TOGA program and fundatmental issue for model validation in general.

季节性赤道大西洋实验(SEQUAL)的目的是解释赤道大西洋对强迫风的反应。开发了一套模型，并在1983-1984年获得了一套非常完整的数据(风、流、温度)。这一建议的目的是研究赤道大西洋动力模式中误差的传播和增长，从观测设定的初始条件和随后的数据同化到新的空间和时间观测。这是TOGA项目的一项重要任务，也是模型验证的基础问题。
