The Mediterranean is recognized among the most responsive regions to climate change, with annual temperatures projected increase by 1–5 °C until 2100. Large cities may experience an additional stress discomfort due Urban Heat Island (UHI) effect. In present study, WRF-ARW numerical weather prediction model was used investigate change impact on UHI for two cities, Rome and Thessaloniki. For this...

In view of the increasing interest in explicit simulation fine-scale features tropical cyclone (TC) boundary layer (TCBL), effects horizontal grid spacing on a 7–10 h an idealized TC are examined using Weather Research and Forecast (ARW-WRF) mesoscale model with one-way moving nests nonlinear backscatter anisotropy (NBA) sub-grid-scale (SGS) scheme. general, reducing from 2 km to 500 m tends pr...

A brief pedagogical survey of the star product is provided, through Groenewold’s original construction based on the Weyl correspondence. It is then illustrated how simple Landau orbits in a constant magnetic field, through their Dirac Brackets, define a noncommutative structure since these brackets exponentiate to a star product—a circumstance rarely operative for generic Dirac Brackets. The ge...

A control synthesis theory was proposed by Horowitz [2] to design a ‘three degrees of freedom’ controller for rate and amplitude constrained systems. Following anti-reset windup techniques, a saturation compensation structure was proposed to design compensators for given linear controllers 131. It is shown here that the compensator can be reformulated in terms of the control synthesis theory. C...

Abstract. The Weather Research and Forecasting (WRF) model offers a multitude of physics parameterizations to study analyze the different atmospheric processes dynamics that are observed in Earth's atmosphere. However, suitability WRF setup is known be highly sensitive type weather phenomena combination parameterizations. A multi-event sensitivity analysis conducted identify general trends suit...
