Abstract: Two different aspect concerning the state-space modeling for atmospheric pollution are dealt with separately in this paper: (i) the treatment of the advection-diffusion equation and (ii) the use of time series analysis. A ...

Abstract: Direct current measurements reveal that the circulation of the northern Gulf of California in the annual timescale consists of a cyclonic basinwide gyre (?0.35 m s?1) that lasts from June to September (4 months), and an ...

Abstract: Wind data collected by two ground stations in a mountainous area are used to investigate the mean properties of the flow on two typical summer days when the wind at the ridgetop had a perpendicular component to the ridge. ...

Abstract: The authors present a chronology of El Niño (EN) events based on documentary records from northern Peru. The chronology, which covers the period 1550?1900, is constructed mainly from primary sources from the city of Trujillo ...

Abstract: The wall-modeled-large eddy simulation (WMLES) technique was used to analyze turbulent flow in a porous medium composed of a staggered arrangement of square cylinders. The study focused on a porosity range of 0.3–0.8 at a ...
