Parameterizing the seasonal–diurnal wind climate of Rome: Fiumicino and Ciampino
Abstract This study uses the Offset Elliptical Normal (OEN) mixture model to parameterize the seasonal–diurnal wind climate of Rome, Italy, for engineering design purposes, and also to reveal the physical meteorology of this “mixed” wind climate. The joint probability density function (PDF) of the…

Advances in Unsupervised Parameterization of the Seasonal–Diurnal Surface Wind Vector
The Offset Elliptical Normal (OEN) mixture model represents the seasonal–diurnal surface wind vector for wind engineering design applications. This study upgrades the parameterization of OEN by accounting for changes in format of the global database of surface observations, improving performance by…

Evaluating the Effects of Disjunct Sampling and Averaging Time on Extreme Synoptic-Scale Wind Speeds
This study evaluates the effects of sampling interval and averaging period on the assessment of extreme synoptic-scale mean wind speeds for structural design, excluding hurricanes and mesoscale events, to focus on correction factors for the standard meteorological observations that are archived for…

Evaluation of XIMIS for Assessing Extreme Pressure Coefficients
Commonly used methods to estimate peak wind pressures on buildings are summarized. The Harris (2009) penultimate XIMIS method is described and calibrated against Gumbel epochal extreme-value analysis (EVA), as well as with the Hermite-Davenport peak factor method by Yang et al. (2013) (YGP) using a…

Leptin Promotes Glioblastoma
The hormone leptin has a variety of functions. Originally known for its role in satiety and weight loss, leptin more recently has been shown to augment tumor growth in a variety of cancers. Within gliomas, there is a correlation between tumor grade and tumor expression of leptin and its receptor…
