Report on Stratosphere Task Force [PDF]

, 2018
Recognising the importance of the stratosphere for skilful seasonal and sub-seasonal prediction, the Stratosphere Task Force was set up in 2016 to improve the representation of the stratosphere in ECMWF forecast and analysis systems.

Variability in Basal Melting Beneath Pine Island Ice Shelf on Weekly to Monthly Timescales [PDF]

, 2018
Ocean‐driven basal melting of Amundsen Sea ice shelves has triggered acceleration, thinning, and grounding line retreat on many West Antarctic outlet glaciers.

Windows of opportunity in subseasonal weather regime forecasting: A statistical–dynamical approach

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study explores how the atmospheric state at initialisation creates windows of opportunity for improving week 3 forecasts of weather regime activity. Greenland blocking activity increases following Madden–Julian Oscillation phases 7, 8, and 1 and weak stratospheric polar vortex states, revealing patterns exploitable by statistical models.

Intercomparison of Assimilated Coastal Wave Data in the Northwestern Pacific Area

Journal of Marine Science and Engineering, 2020
The assimilated coastal wave data are useful for wave climate study, coastal engineering, and design for marine disaster protection. However, the assimilated coastal wave data are few.

A pilot variational coupled reanalysis based on the CESAM climate model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

The role of soil moisture in the inland penetration of Indian monsoon low‐pressure systems

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We use the Advanced Weather Research and Forecasting model to examine the role of soil moisture in the inland penetration of Indian monsoon low‐pressure systems (LPSs). We find that LPSs penetrate deeply into India despite a dry land surface; however, their inland penetration is adversely affected when there is a reduction in the total surface heat ...

COVID-19 causes record decline in global CO2 emissions [PDF]

, 2020
The considerable cessation of human activities during the COVID-19 pandemic has affected global energy use and CO2 emissions. Here we show the unprecedented decrease in global fossil CO2 emissions from January to April 2020 was of 7.8% (938 Mt CO2 with a

Estrous behavior in dairy cows: identification of underlying mechanisms and gene functions [PDF]

, 2010
Selection in dairy cattle for a higher milk yield has coincided with declined fertility. One of the factors is reduced expression of estrous behavior. Changes in systems that regulate the estrous behavior could be manifested by altered gene expression ...

Assessing the impact of model biases on subseasonal forecast skill

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Relaxation experiments where the nudging was performed towards bias‐corrected integrations of the same model display significantly improved skill at weeks 3 and 4, particularly in the northern extratropics. This indicates that there is a large potential for improving dynamical subseasonal forecasting skill by improved treatment of model biases.

Variability of the Pechora Sea Ice Area and Its Correlation With the Barents Sea Surface Temperature According to Satellite Observations and Reanalysis

Лëд и снег
Variability of the Pechora Sea ice cover and the Barents Sea surface temperature during the season from October to June in 2002–2022 (except the season of 2011/2012) was studied on the basis of satellite observations and reanalysis ERA5. Influence of the
