ABSTRACT: Ice storms and freezing rain events significantly disrupt transportation and power infrastructure, posing serious risks to public safety. This study investigates the environmental conditions conducive to freezing rain and assesses how current climate models simulate these environments. We employ an ensemble precipitation typing approach utilizing three established algorithms (Bourgoui…
ABSTRACT: Bias correction (BC) is commonly used to refine dynamical climate model results for use in applied research. However, uncertainties linked to the BC of multivariate meteorological indices, crucial for many applied research applications, are often underappreciated. Focusing on daily maximum values of the multivariate heat index (HI, a function of temperature and relative humidity), thi…
ABSTRACT: Gust factors are widely used in engineering applications to adjust wind data to standard siting and roughness conditions. Multiyear average gust factors have been typically applied in the applications. Using 1-min Automated Surface Observing System (ASOS) data from over 500 stations in the contiguous United States, the gust factor record is assessed for significant discontinuities usi…
ABSTRACT: The study presents a comprehensive analysis of long-term climate trends in Setif, Algeria, a representative semiarid highland station, using a 125-yr dataset (1900-2024) of monthly and annual precipitation and maximum and minimum temperature. Given the discontinuities in the historical dataset, two neighboring reference stations (Batna and Constantine) and three imputation methods wer…
ABSTRACT: This study conducts numerical simulations using the Weather Research and Forecasting (WRF) Model to evaluate the impact of urbanization on precipitation in the Osaka metropolitan area, a megacity adjacent to the sea and mountains. The simulations were conducted for 320 events on which convective precipitation was likely to occur. The results of the control (CTRL) experiment, which use…
ABSTRACT: A gridded wet-bulb globe temperature (WBGT) climatology for the southeastern United States is presented, emphasizing athlete and worker safety thresholds. Hourly WBGT estimates are derived from the land component of the fifth generation European Centre for Medium-Range Weather Forecasts atmospheric reanalysis (ERA5-Land) and validated using U.S. Climate Reference Network estimates fro…
ABSTRACT: The marine atmospheric boundary layer influences the evolution of evaporation duct height (EDH) by altering the vertical profile of the refractive index. The EDH is a crucial parameter for marine and naval communication. Many studies have demonstrated the sensitivity of boundary layer similarity theory in estimating the vertical profile of refractive index. The current study modifies …
