摘要

本研究的作者回顾了BMI中相对于Qian、Im和elahmad和Alfahmi et al有限面积研究结果的定性性能收敛测试。地表风的融合和地表风的异常是用有限的差异来计算的。研究结果表明，ERA5模型能够模拟雷焦区域气候模型(RegCM)和爪哇岛及其周边和西部BMI的27公里(27英里)分辨率的表面信风异常的收敛，并具有更高的收敛值。但是对于东部BMI的天气研究模型(WRF)，橡皮分析模型也可以模拟表面风的收敛，但分数较低。此外，橡皮5分析模型模拟了BMI西部和东部风的趋同速度比MRCM27和WRF快2小时。根据这项研究，我们讨论了以5个表面表面的风面结果为基础的印尼海关区域研究的资格证书。风面收敛，风面反常收敛是通过彻底的不同来计算的。结果显示，风表面的再分析可以模拟风表面的区域气候模型(RegCM)和27公里外的气候模型(MRCM)与Java的区域气候模型(MRCM)以及以及更高层次的智能收敛。虽然ERA5模型分析还可以同时进行surface winds的模拟会议，但在BMI东部的低价值天气研究中，低价值模型也可以进行9公里的天气研究。此外，我们将分析风边表面和东方BMI与MRCM27和WRF的两个小时。

PERFORMA KONVERGENSI ANGIN PERMUKAAN DIURNAL MODEL REANALISIS ERA5 DI BENUA MARITIM INDONESIA

IntisariPada penelitian ini, penulis mengkaji uji performa kualitatif konvergensi angin permukaan model reanalisis ERA5 di BMI yang dibandingkan dengan hasil penelitian menggunakan limited area model (LAM) oleh Qian, Im dan Eltahir serta Alfahmi et al. Konvergensi angin permukaan dan anomali angin permukaan dihitung dengan menggunakan finite difference. Hasil penelitian menunjukkan bahwa model reanalisis ERA5 mampu mensimulasikan konvergensi anomali angin permukaan dengan baik terhadap model regional climate model (RegCM) maupun The MIT regional climate model (MRCM) resolusi 27 km di Pulau Jawa dan sekitarnya serta BMI bagian barat dengan nilai konvergensi yang lebih tinggi. Sedangkan terhadap model weather research forecast (WRF) 9 km di BMI bagian timur, model reanalisis ERA5 juga dapat mensimulasikan konvergensi angin permukaan, tetapi dengan nilai yang lebih rendah. Selain itu, model reanalisis ERA5 mensimulasikan konvergensi angin permukaan lebih cepat 2 jam di BMI bagian barat dan timur dibandingkan MRCM27 dan WRF. AbstractIn this study, we discuss the qualitative performance testing of ERA5 surface wind convergence over the Indonesia maritime continent (BMI) compared with research based on limited area model (LAM) by Qian, Im, and Eltahir and also Alfahmi et al. Wind surface convergence and wind surface anomalies convergence is calculated using finite-difference. The results show that the ERA5 reanalysis model can simulate convergence of surface wind anomalies compared with both regional climate model (RegCM) and 27 km MIT regional climate model (MRCM) over Java and also western BMI with higher convergence values. While ERA5 reanalysis model can also simulate convergence of surface winds, but with lower values compared to 9 km weather research forecast (WRF) model over eastern BMI. Besides, the ERA5 reanalysis model simulates convergence of surface winds, which is 2 hours faster over western and eastern BMI compared to MRCM27 and WRF.
