Here we present an observational study of the variations in the stratospheric polar vortex (SPV) associated with the main tropospheric circulation patterns in the Northern Hemisphere in winter (November to March). The circulation patterns are based o...
Atmospheric turbulence is a major hazard for commercial flight operations. As a result, reliable and easily interpretable meteorological forecast data for this hazard is paramount to the safety of aircraft, crew and passengers. To meet this requireme...
Baghdad, Iraq, is among the most polluted cities in the Middle East, yet it lacks a public PM2.5 monitoring network. This study analyzed eight years (2017–2024; n = 416) of gravimetric PM2.5 measurements and their relationship with five meteoro...
Short-term drought forecasting remains challenging in Mediterranean regions because of strong interannual climate variability. This study develops and verifies an integrated framework for one- to three-month-ahead forecasting of meteorological drough...
Heat is now one of the leading weather-related causes of death worldwide, and unlike a flood or a storm, its damage rarely arrives in a single moment. It accumulates, mostly indoors and mostly at night, through physiological stress that builds across...
Accurate Quantitative Precipitation Estimation (QPE) is a critical imperative for hydrological modeling, disaster risk reduction and optimized irrigation scheduling in smart agriculture, yet it remains a significant challenge in topographically compl...
As an important grain-producing region of China, Anhui Province suffered its most severe drought in 70 years in 1978, particularly in summer. During the drought, the west–northward shifted western Pacific subtropical high (WPSH) induced local h...
We evaluate binary rainfall occurrence classification in southern Thailand using 00 UTC radiosonde profiles from Phuket Airport and rainfall observations at Phuket, Krabi, Takua Pa (Phang-nga) and Nakhon Si Thammarat. Of 2631 soundings from 2011 to 2...
The summer of 2012 in Europe was characterized by sharp contrasts in precipitation. The United Kingdom recorded its wettest summer season (June–August) since 1912. Spain faced drought and wildfires, as summer precipitation levels there were the...
This study introduces a physics-based dynamic constraint for the asymptotic allowable mixing length, implemented in the latest upgrade of NOAA’s operational Hurricane Analysis and Forecast System (HAFS) v2.2. Replacing conventional fixed-value...
This study evaluated satellite-based precipitation in Bolivia using a combination framework with four equations: relative error, geometric, weighted linear, and sigmoidal. These were compared to enhance daily GSMaP_Gauge V8 estimates. Considering ele...
Lake-effect snow (LES) has traditionally been studied from a mesoscale perspective, with comparatively less attention devoted to the role of synoptic-scale forcing. This study quantifies the prevalence and magnitude of synoptic forcing during 116 hea...
In this work, the climatological character of simultaneously occurring blocking events will be examined. Some previously published papers have proposed without strong evidence that simultaneously occurring blocking events are stronger and more persis...
