Wind Induced Composition Effects at High Latitudeses. As a feedback mechanism, advective mass transport completely changes the “primary” composition effects induced by eddy diffusion. Owing to the rotational nature of EXB momentum coupling its signature in composition is comparatively weak, and clearly distinguishable from the effects of Joule dissipation.作者: 評(píng)論者 時(shí)間: 2025-3-26 01:06
