DOI: 10.1002/2016jd026008
Abstract: We present a combination of satellite observation and high-resolution model output to understand monsoon convection as a source of high-latitude mesospheric gravity waves (GWs). The GWs generated over the Northern Hemisphere (NH) monsoon region during… read more here.

DOI: 10.1007/s10452-017-9642-3
Abstract: Variation in biological communities is a consequence of stochastic and deterministic factors. Examining the relative importance of these factors helps to understand variation in the whole biodiversity in a region. We examined the roles of… read more here.

DOI: 10.1016/j.epsl.2017.09.012
Abstract: Abstract Understanding the origin and evolutionary history of drought events is of great significance, providing critical insight into future hydrological conditions under the changing climate. Due to the scarcity of drought proxies from northern China,… 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.jembe.2018.08.004
Abstract: Many species of marine mammals have evolved behavioural adaptations to minimize heat loss to the surrounding water. We tracked 21 dugongs (Dugong dugon Muller 1776) using acoustic and satellite/GPS transmitters in 2012, 2013 and 2014… read more here.
