Wind shear and turbulence simulation [PDF]

The aviation community is increasing its reliance on flight simulators. This is true both in pilot training and in research and development. In moving research concepts through the development pipeline, there is a sequence of events which take place ...

Intensification of Flash and Long‐Term Droughts in the Danube River Basin: A Multi‐Scale Analysis Using Satellite‐Derived Evaporative Stress Index and Soil Water Index

International Journal of Climatology, EarlyView.
Analysed drought intensification in the Danube using Evaporative Stress Index (ESI) and Soil Water Index (SWI). Flesh drought detection: developed thresholds for rapid drought detection using ESI‐4Wk and SWI‐40. Multi‐layer analysis: combined atmospheric stress and soil moisture to assess drought impacts.

Stochastic Modelling of Daily Precipitation in Semi‐Arid Regions Using Markov Chains and Parametric Distributions

International Journal of Climatology, EarlyView.
This study applies stochastic rainfall models combining Markov Chains with gamma and mixed exponential distributions to a semi‐arid climate in Northeast Brazil. Model structures were evaluated using Bayesian Information Criterion (BIC), with maximum likelihood (MLM) for parameter estimation and cumulative distribution functions (CDFs) for validation ...

Post‐Processed CMIP6 Climate Projections for Hydro‐Environmental Risk Assessment in the Middle East and Central Asia

International Journal of Climatology, EarlyView.
Estimating water resources is important for regional climate impact analysis and risk estimation. The Middle East and Central Asia have largely reached the limit of sustainably usable water across their river basins and ecosystems. Strategies designed to mitigate environmental risks require a reliable estimation of water availability trends.

Practicality of electronic beam steering for MST/ST radars, part 6.2A [PDF]

Electronic beam steering is described as complex and expensive. The Sunset implementation of electronic steering is described, and it is demonstrated that such systems are cost effective, versatile, and no more complex than fixed beam alternatives ...

Assessing Climate Change Impacts on Runoff Variability and Extremes in China Using High‐Resolution Simulations

International Journal of Climatology, EarlyView.
Future runoff in China shows strong regional and seasonal disparities, with the Southeast basin seeing the largest increase in annual runoff. Wetter summers and drier winters are expected in the south, whilst the northwest will face the opposite. Over 56% of regions are expected to experience more extreme high runoff, and over 40% face intensified low ...

Seasonal Variability of Key Climate Parameters in the Mediterranean Region: Distinct Features From A Long‐Term (1940–2023) Analysis

International Journal of Climatology, EarlyView.
The intra‐annual variability of the Mediterranean climate does not include an even transition from winter to summer regime and vice versa. A detailed examination of the long‐term (84 years) mean intra‐annual variations of key parameters reveals remarkable and climatologically important peculiarities. ABSTRACT The intra‐annual variability of atmospheric

Mapping the Spatial Scales of Australian Extreme Precipitation Using Daily Rain Gauges

International Journal of Climatology, EarlyView.
We present the first continent‐wide analysis of the spatial scales of daily extreme precipitation events (EPEs) in Australia using station observations and semivariogram analysis. EPEs generally have larger spatial scales at higher latitudes, with strong seasonal and regional differences shaped by topography, meteorological regimes, and climate ...
