The sensitivity of different atmospheric forcing on the simulation of Sea Surface Temperature (SST) in the Indian Ocean is examined using Regional Ocean Modeling System (ROMS). Model simulations using three different atmospheric forcings from the National Centers for Environmental Prediction (NCEP; 2.5 deg), National Centre for Medium Range Weather Forecasting (NCMRWF; 0.25 deg) and TropFlux (0.5 deg) are analyzed here. Model sensitivity to the atmospheric forcing is studied by analyzing the response of SST and mixed layer depth (MLD) using statistical methods. Results show that the response of NCMRWF and TropFlux forcing was almost similar in capturing the variability of SST in comparison with the corresponding observations. But NCEP was unable to capture SST variability, especially over the central part of the Arabian Sea (AS). It is shown that deeper MLD simulations by NCEP forcing due to the high magnitude of wind resulted in an unrealistic simulation of SST.

使用区域海洋模拟系统 (ROMS) 检查了不同大气强迫对印度洋海面温度 (SST) 模拟的敏感性。此处分析了使用来自国家环境预测中心 (NCEP；2.5 度)、国家中期天气预报中心 (NCMRWF；0.25 度) 和 TropFlux (0.5 度) 的三种不同大气强迫的模型模拟。通过使用统计方法分析 SST 和混合层深度 (MLD) 的响应来研究模型对大气强迫的敏感性。结果表明，与相应的观测相比，NCMRWF 和 TropFlux 强迫的响应在捕捉海温变化方面几乎相似。但是 NCEP 无法捕获 SST 的变化，尤其是在阿拉伯海 (AS) 的中部。
