摘要

Abstract

西北太平洋副热带高压(NWPSH)对东亚天气和气候具有重要影响,其强度和位置的预测至关重要.本研究旨在评估卷积长短期记忆(ConvLSTM)模型提前3个月对夏季500 hPa位势高度及NWPSH强度和面积的预测性能,并将其与动力模式南京信息工程大学气候预测系统1.0版(NUIST-CFS1.0)和加拿大季节-年际预测系统第2版(CanSIPSv2)预测结果对比.评估指标为纬度加权均方根误差(RMSEw),异常相关系数(ACC)和NWPSH指数.在夏季平均和逐月预测中,ConvLSTM模型对西太平洋地区500 hPa位势高度的RMSEw和ACC预测技巧均优于动力模式.ConvLSTM模型预测的NWPSH强度指数与观测值的相关系数高于动力模式结果,预测的NWPSH面积指数也表现出更稳定的性能.与两个动力学模式相比,ConvLSTM模型在8月的改进更为显著,表明其对夏季末期环流形势具有更强的捕捉能力.因此,ConvLSTM模型在夏季NWPSH的预测中具有较好的应用潜力,为该区域的气候预测提供了新的视角和方法.
