recommendations! Published in 2017 at "Social Work"

DOI: 10.1002/2016sw001546

Abstract: We compare D and lower E region ionospheric model calculations driven by the Whole Atmosphere Community Climate Model (WACCM) with a selection of electron density profiles made by sounding rockets over the past 50 years.… read more here.

DOI: 10.1002/2017ja024089

Abstract: Effects of subgrid-scale gravity waves (GWs) on the diurnal migrating tides are investigated from the mesosphere to the upper thermosphere for September equinox conditions, using a general circulation model coupled with the extended spectral nonlinear… read more here.

DOI: 10.1002/joc.8719

Abstract: In this study, the effects of the Mount Pinatubo eruption on surface air temperature (SAT) over mid‐ to high‐latitude Northern Hemisphere (NH) continents in December–January–February (DJF) 1991/92 were investigated using MPI‐ESM Grand Ensemble simulations, observations… read more here.

DOI: 10.1007/s11207-020-01728-7

Abstract: In this article, we present a study of the perturbations occurring in the Earth’s environment on 7 October 2015. We use a multi-instrument approach, including space and ground observations. In particular, we study the ionospheric… read more here.

DOI: 10.1016/j.epsl.2019.05.025

Abstract: Abstract Specific challenges still exist in our understanding of past greenhouse climate states. Whilst climate model simulations using atmospheric CO2 concentrations consistent with proxy estimates broadly align with lower latitude proxy temperature estimates, they struggle… read more here.

DOI: 10.1016/j.gloplacha.2019.103025

Abstract: Abstract Sea surface temperature (SST) of the modern Yellow Sea (YS) is sensitive to forcing by both the East Asian monsoon and the North Pacific western boundary current, however, detailed mechanisms for explaining the Holocene… read more here.

DOI: 10.1016/j.icarus.2016.10.006

Abstract: Abstract Shallow water simulations are used to present a unified study of three major storms on Saturn (nicknamed as Great White Spots, GWS) at different latitudes, polar (1960), equatorial (1990), and mid-latitude (2010) (Sanchez-Lavega, 2004;… read more here.

DOI: 10.1016/j.jaridenv.2017.07.004

Abstract: Abstract Because of the lack of leaves, the distributions of columnar cacti are limited by their capacity to trade off their photosynthetic chlorenchyma and their non-photosynthetic storage parenchyma. For species with wide latitudinal ranges, variations… read more here.

DOI: 10.1016/j.jastp.2018.02.003

Abstract: Abstract The equatorial- and low-latitude thermospheric dynamics is affected by both equatorial electrodynamics and neutral wave dynamics, the relative variation of which is dependent on the prevalent background conditions, which in turn has a seasonal… read more here.
