APAKAH MAKSUD DOWNDRAUGHT dalam CORSICA?
Draf menegak
Pengemaskinian atau downdraft adalah pergerakan menegak udara sebagai fenomena yang berkaitan dengan cuaca. Salah satu daripada dua kuasa menyebabkan udara bergerak. Kawasan tempatan yang hangat atau sejuk akan menunjukkan pergerakan menegak. Jisim hawa hangat biasanya akan kurang padat daripada kawasan sekitarnya, dan akan meningkat sehingga ia mencapai udara yang lebih panas atau kurang padat daripada dirinya sendiri. Perbualan akan berlaku untuk jisim udara sejuk, dan dikenali sebagai penenggelaman. Pergerakan jumlah besar udara ini, terutamanya apabila kawasan kenaikan udara panas, basah dapat membuat awan besar, dan merupakan penyebab utama ribut petir. Draf juga boleh dibuat oleh kawasan tekanan rendah atau tinggi. Rantau tekanan rendah akan menarik udara dari kawasan sekitarnya, yang akan bergerak ke arah pusat dan kemudian naik, mewujudkan pengemaskinian. Kawasan tekanan tinggi kemudiannya akan menarik udara dari kawasan sekitarnya, yang akan bergerak ke tengah dan tenggelam, mewujudkan downdraft. Kemas kini dan downdraf, bersama-sama dengan ricih angin pada amnya, adalah penyumbang besar kepada kemalangan pesawat semasa berlepas dan mendarat di dalam ribut petir. Kes-kes yang melampau, yang dikenali sebagai kemurungan dan mikroburst boleh mematikan dan sukar untuk diramalkan atau diperhatikan.
