Hujan es sudah terjadi beberapa kali di Jakarta. Hujan es terjadi lagi di Jakarta Pusat(sekitar Jl. Thamrin) pada tanggal 20 April 2000 pukul 15:15 wib. Kejadian ini seperti taklazim terjadi di Jakarta mengingat Jakarta terletak di wilayah equator. Selain itu, hail sangat jarang terjadi meskipun kilat (badai guntur) sering terjadi di Indonesia. Tulisan iniakan menjelaskan mekanisme terbentuknya hujan es (hail) dalam awan badai, bagaimana hujan es dapat terjadi di Jakarta, dan analisa kondisi cuaca yang mendukung terjadinya hujan es di Jakarta pada tanggal 20 April 2000.Hail has occurred several times in Jakarta. Hail taken place again in Central Jakarta (Jl.Thamrin and vicinity) on 20 April 2000 at 15:15 Western Indonesia Standard Time. It seems unusual event that hail occurs in Jakarta considering that Jakarta is located within equatorial belt. Moreover, hail is hardly to come about even lightnings (thunderstorms)are frequently to occur in Indonesia. This paper will describe the mechanism of hail formation within cloud, how hail could occur in Jakarta, and weather condition analysis that supports hail incidence in Jakarta on 20 April 2000.
