Numerical simulations are performed to assess the influence of horizontal and vertical model resolution on the turbulent erosion of a cold-air pool (CAP) by foehn winds in an Alpine valley near Innsbruck, Austria. Strong wind shear in the t...
Impacts of model resolution and ocean coupling on mean and eddy momentum transfer during the rapid intensification of super-typhoon Muifa (2011) [0.03%]
模式分辨率和海洋耦合对超强台风梅花快速增强期间平均流和eddies动量输送的影响

Yang Yu et al.
This study uses a coupled atmosphere-ocean model with different numerical settings to investigate the mean and eddy momentum transfer processes responsible for Typhoon Muifa's (2011) early rapid intensification (RI). Three experiments are c...

Heatwaves are weather events characterized by extreme near-surface temperature anomalies that persist for several days, and therefore lead to catastrophic impacts on natural ecosystems, agriculture, human health, and economies. Different ph...
Spatial variability of forward modelled attenuated backscatter in clear-sky conditions over a megacity: Implications for observation network design [0.03%]
晴空条件下特大城市后向散射衰减的空间变化：对观测网络设计的启示
Elliott Warren,Cristina Charlton-Perez,Humphrey Lean et al.
Elliott Warren et al.
Sensors that measure the attenuated backscatter coefficient (e.g., automatic lidars and ceilometers [ALCs]) provide information on aerosols that can impact urban climate and human health. To design an observational network of ALC sensors fo...

Covariance between meridional wind and air temperature in the lower troposphere quantifies the poleward flux of dry static energy in the atmosphere; in the midlatitudes, this is primarily realised by baroclinic weather systems. It is shown ...
Planetary, inertia-gravity and Kelvin waves on the f-plane and [Formula: see text] -plane in the presence of a uniform zonal flow [0.03%]

A novel particle filter proposed recently, the particle flow filter (PFF), avoids the long-existing weight degeneracy problem in particle filters and, therefore, has great potential to be applied in high-dimensional systems. The PFF adopts ...
