The Dependence of Cold and Hot Patches on Local Plasma Transport and Particle Precipitation in Northern Hemisphere Winter by Duan Zhang, Qing‐He Zhang, Y.‐Z. Ma, Kjellmar Oksavik, L. R. Lyons, Zan‐Yang Xing, Marc Hairston, Z.‐X. Deng, J.‐J. Liu

“…Abstract By using a database of 4,634 cold patches (high density and low electron temperature) and 4,700 hot patches (high density and high electron temperature) from Defense Meteorological Satellite Program F16 in 2005–2018 winter months (October–March), we present a statistical survey of the distributions of polar cap patches for different interplanetary magnetic field (IMF) orientations and ionospheric convection geometries. We investigate the dependence of cold and hot patches on local plasma transport and soft‐electron precipitation. …”
