Analysis of the Causes and Wind Field Structure of a Dry Microburst in a Weak Weather Background

Atmosphere, 2023
Dry microbursts in weak weather backgrounds, due to their small scale and general lack of precipitation, are often difficult to observe using weather radar. On the night of 26 April 2023, a dry microburst occurred at the Yinchuan Airport.

Identification and characterization of foehn events in Beijing and their impact on air pollution episodes [PDF]

Atmospheric Chemistry and Physics
This study proposes a method for identifying foehn events in Beijing using automatic weather station (AWS) data, considering upper-air wind direction, topography, meteorological changes, and foehn propagation.

Foehn winds influence surface ablation on Glaciar Perito Moreno, southern Patagonian icefield

Journal of Glaciology
The southern Patagonian glaciers are known for having extremely high ablation rates. Foehn winds are one of the suspected causes, however, their influence on the annual ablation, their interannual variations, and their relationship with climate change is

Foehn-like Wind in the Mountains of Southeastern Brazil as Seen by the Eta Model Simulation [PDF]

Revista Brasileira de Meteorologia, 2020
The present study gives evidence of the occurrence of foehn-like wind on the eastern slopes of the mountains at Southeastern Brazil. A particular case was detected based on observational evidence on 4 July 2015 near the city of Cruzeiro, state of Sao ...

Spatiotemporal Characteristics and Synoptic Patterns of Dry‐Hot Winds (Sukhoviys) in Ukraine

International Journal of Climatology, EarlyView.
This study analyses dry‐hot winds, or sukhoviys, a recurrent phenomenon during the warm season across Ukraine that contributes to rapid moisture loss from soil and vegetation. The activity of sukhoviy events was assessed using the introduced Sukhoviy Station Index, accounting for their meteorological characteristics and frequency of occurrence.

ERA5 Can Overstate Changes in the Frequency of Extreme Heat: A New Zealand Case Study

International Journal of Climatology, EarlyView.
ERA5 reproduces broad patterns of summer warming across New Zealand but underestimates temperature variability and warm‐tail extremes, biasing estimates of extreme heat risk. ABSTRACT Summertime temperature extremes exert profound impacts on human health, ecosystems, and infrastructure, yet their characteristics and drivers remain poorly quantified in ...
