Kemiringan angin

Kemiringan angin atau gradien angin atau secara lebih spesifik kemiringan kecepatan angin^[1][2] atau pergeseran angin^[3] adalah tingginya kemiringan ke arah vertikal pada rata-rata kecepatan angin ke arah horisontal di bawah atmosfer.^[4] Kemiringan angin merupakan tingkat tingkat kenaikan kekuatan angin dengan unit peningkatan ketinggian di atas permukaan tanah.^[5][6] dalam satuan metrik. Kemiringan angin sering diukur dalam satuan meter per detik kecepatan, per kilometer ketinggian (m / s / km ), yang mengurangi unit standar kecepatan geser, (s⁻¹).

Thus we have a “wind-speed gradient” as we move vertically, and this has a tendency to encourage mixing between the air at one level and the air at those levels immediately above and below it.  line feed character di |quote= pada posisi 84 (bantuan)
