Quarterly Journal of the Royal Meteorological Society, EarlyView.This study develops a method to identify the source areas of precipitation events, as illustrated for the western part of the Netherlands. Radar‐based precipitation data are traced back to their source areas and machine‐learning techniques are used to identify hypothesized causes: urban heat, surface roughness, and air pollution. We find that urban and

Diagnosing the 11‐year solar cycle's influence on the East Atlantic pattern
Quarterly Journal of the Royal Meteorological Society, EarlyView.A previously unidentified solar‐cycle response in the East Atlantic pattern is found in late winter at lag +3 years with larger amplitude than the NAO response. A statistically significant NAO response to the solar cycle is seen in late winter at lag 0 years.

Quarterly Journal of the Royal Meteorological Society, EarlyView.We document the protocol and first results from the first ever coordinated multimodel variable‐resolution experiment set with refinement over the polar regions. We find that the refinement generally yields model‐dependent effects. The most consistent improvement is an amelioration of the upper‐level cold bias in the polar regions that translates into ...

Fumed Silica Particle Deagglomeration Associated with Instrument Techniques
International Journal of Occupational Hygiene, 2018 Fumed silica, due to the thixotropic properties and low thermal conductivity, is used in insulation products. Exposure to crystalline silica is of most concern and there is also evidence that exposure to nanometer-sized fumed silica may lead to adverse ...

Modulation of wind drag by tidal currents in an embayment
Quarterly Journal of the Royal Meteorological Society, EarlyView.Tidal currents modulate how wind energy enters the surface wave field by influencing both wave drag and wave generation. In Shark Bay, following currents reduce effective wave steepness and wind drag, and opposing currents enhance wave growth. Wind energy is partitioned between wave drag and the creation of new waves, explaining observed tidal ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.In this study, the synoptic conditions for modes of mesoscale convective systems (MCSs) in South Korea are generalized based on composite analysis. The preferred precipitation region, synoptic patterns, moisture transport, sea surface temperature and thermodynamic and dynamic instabilities are characterized according to four modes: convective cells (CC)

Exploiting Aeolus winds in a regional numerical weather prediction model
Quarterly Journal of the Royal Meteorological Society, EarlyView.Aeolus measured winds have proven to be beneficial for global models. However, demonstrating positive impact for limited‐area models has been a challenge so far. For the first time, we have demonstrated a statistically significant positive impact of Aeolus winds in a limited‐area model by using the 4DVar data assimilation technique and the most recent ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.We document for the first time how the assimilation of CS2SMOS observations improves the model representation of Arctic sea‐ice thickness (SIT) and its variability: biases are reduced (top row), while excessive variability in the Beaufort Sea and lack of variability in the ice pack are both corrected (bottom row).

Turbulence Model Selection in Numerical Simulation of Gas-liquid Cylindrical Cyclone
Shiyou jixie, 2017 Numerical simulation is an effective method to study the separation performance of deep-water gas-liquid cylindrical cyclone. The selection of turbulence model will directly affect the accuracy of numerical simulation.
