Hybrid versus global thermostatting in molecular-dynamics simulation of methane-hydrate crystallisation

引用

Chinese Journal of Chemical Engineering 2019年第9期27卷 2180-2188页

作者： Niall J.english Mohammad Reza Ghaani School of Chemical and Bioprocess Engineering University College Dublin

Molecular-dynamics(MD)simulations have been performed for the growth of a spherical methane-hydrate nano-crystallite,surrounded by a supersaturated water–methane liquid phase,using both a hybrid and globalsystem thermostatting *** was found that hybrid thermostatting led to more sluggish growth and the establishment of a radial temperature profile about the spherical hydrate crystallite,in which the growing crystal phase is at a higher temperature than the surrounding liquid phase in the interfacial region,owing to latent-heat *** addition,Onsager’s-hypothesis fluctuation–dissipation analysis of fluctuations in the number of crystal-state water molecules at the interface shows slower growth.

Assimilation of Feng-Yun-3B Satellite Microwave Humidity Sounder Data over Land

引用

Advances in Atmospheric Sciences 2018年第3期35卷 268-275页

作者： Keyi CHEN Niels BORMANN Stephen english Jiang ZHU School of Atmospheric Sciences Chengdu University of Information & Technology Chengdu Sichuan 610225 China International Centre for Climate and Environment Sciences Institute of Atmospheric Physics China Beijing 100029 China European Centre for Medium-Range Weather Forecasts Reading RG2 9AX UK

The ECMWF has been assimilating Feng-Yun-3B （FY-3B） satellite microwave humidity sounder （MWHS） data over ocean in an operational forecasting system since 24 September 2014, It is more difficult, however, to assimilate microwave observations over land and sea ice than over the open ocean due to higher uncertainties in land surface temperature, surface emissivity and less effective cloud screening. We compare approaches in which the emissivity is retrieved dynamically from MWHS channel l [150 GHz （vertical polarization）] with the use of an evolving emissivity atlas from 89 GHz observations from the MWHS onboard NOAA and EUMETSAT satellites. The assimilation of the additional data over land improves the fit of short-range forecasts to other observations, notably ATMS （Advanced Technology Microwave Sounder） humidity channels, and the forecast impacts are mainly neutral to slightly positive over the first five days. The forecast impacts are better in boreal summer and the Southern Hemisphere. These results suggest that the techniques tested allow for effective assimilation of MWHS/FY-3B data over land.
