DOI: 10.1007/s13351-020-0007-9
Abstract: In a sharp contrast to tropical cyclone (TC) genesis over the main development region of the western North Pacific (WNP), near-equatorial (0°–5°N) TCs exhibit a distinctive annual cycle, peaking in boreal winter and being inactive… read more here.

DOI: 10.1016/j.epsl.2021.116949
Abstract: Abstract In plate tectonic theory a weak asthenosphere is required to facilitate the motions of the rigid plates. Partial melt could weaken the mantle, in turn impacting convection, but to date the existence of persistent… read more here.

DOI: 10.1134/s0016793218060142
Abstract: The generation of the U-shaped spectrum, an unusual wave phenomenon observed in the equatorial part of the DEMETER satellite orbit, is studied. This wave phenomenon is explained for the first time based on the assumption… read more here.
