Quarterly Journal of the Royal Meteorological Society, EarlyView.ICON outperforms COSMO in simulating a south foehn event in the Alpine Rhine Valley, with improved accuracy in temperature, wind speed, and foehn timing. This enhanced performance likely results from a more accurate representation of surface energy balance and gravity wave pattern on the lee side of the mountain.

Erosion due to impingement of cavitating jet.
Hydraulics & Pneumatics, 1987 Cavitation erosion produced by impingent of cavitating jet was experimentally studied with specimens of aluminum alloy in high water base fluid of chemical solution type and tap water. Furthermore, the behavior of impinging cavity clouds was observed through instantaneous photographs.

Noise of the Harrier in vertical landing and takeoff [PDF]
The noise of the Harrier AV8C aircraft in vertical takeoff and landing was measured 100 feet to the side of the aircraft where jet noise dominates. The noise levels were quite high - up to 125 dB overall sound level at 100 feet.

Quarterly Journal of the Royal Meteorological Society, EarlyView.State‐of‐the‐art, convection‐permitting NWP models reproduced the main features of the October 22–23, 2019 heavy precipitation event in Catalonia. However, slight configuration changes yielded varying streamflow responses and statistical performance, highlighting the challenge of simulating these events in Mediterranean medium‐sized basins ...

Study of Lubricant Jet Flow Phenomena in Spur Gears: Out of Mesh Condition [PDF]
Oil jet lubrication on the disengaging side of a gear mesh was analyzed. Results of the analysis were computerized and used to determine the oil jet impingement depth for several gear ratios and oil jet to pitch line velocity ratios.

Indian and African monsoons: Trajectories and interactions
Quarterly Journal of the Royal Meteorological Society, EarlyView.The catch basin of marine air particles of the Indian monsoon is the tropical Indian ocean, whilst that of the African monsoon is the east tropical Atlantic. However, the oscillations induced by the monsoonal interactions favour particle exchange between the two basins. These transitions are abrupt in the presence of stochastic resonance. The monsoonal

Into Mesh Lubrication of Spur Gears with Arbitrary Offset Oil Jet. 2: for Jet Velocities Equal to or Greater than Great Velocity [PDF]
An analysis was conducted for into mesh oil jet lubrication with an arbitrary offset and inclination angle from the pitch point for the case where the oil jet velocity is equal to or greater than gear pitch line velocity.

Observations and numerical simulations of a valley‐exit wind in the Alpine Bolzano basin
Quarterly Journal of the Royal Meteorological Society, EarlyView.The evolution and spreading of the nocturnal valley‐exit wind flowing from the Isarco Valley into the Bolzano basin, in the Italian Alps, are found to be influenced by the basin temperature stratification. Measurements and high‐resolution simulations show that a cold‐air pool favors an upward trajectory of the flow at the exit of the valley.

Jet array impingement with crossflow-correlation of streamwise resolved flow and heat transfer distributions [PDF]
Correlations for heat transfer coefficients for jets of circular offices and impinging on a surface parallel to the jet orifice plate are presented. The air, following impingement, is constrained to exit in a single direction along the channel formed by ...
