Abstract Emerging application areas such as air pollution in megacities, wind energy, urban security, and operation of unmanned aerial vehicles have intensified scientific societal interest mountain meteorology. To address needs help improve the prediction weather, U.S. Department Defense has funded a research effort—the Mountain Terrain Atmospheric Modeling Observations (MATERHORN) Program—that draws expertise multidisciplinary, multi-institutional, multinational group researchers. The...
This work presents the characterisation and comparison of daytime nighttime mountain breezes observed at three sites through analysis tower data. The are located: (i) in foothills Guadarrama Mountains Spain, (ii) on a plateau adjacent to Pyrenees France, (iii) Salt Lake Valley (SLV) southwest United States. thermally-driven winds detected systematic algorithm which considers both synoptic local meteorological conditions. characteristics depend scale breeze each site.

Abstract. Ground-based measurements of frozen precipitation are heavily influenced by interactions surface winds with gauge-shield geometry. The Multi-Angle Snowflake Camera (MASC), which photographs hydrometeors in free-fall from three different angles while simultaneously measuring their fall speed, has been used the field at multiple midlatitude and polar locations both without wind shielding. Here, we present an analysis Arctic observations – a Belfort double Alter shield compare results...
Abstract The Spring Predictability Barrier (SPB) phenomenon is characterized by the reduced accuracy of El Niño/Southern Oscillation (ENSO) forecasts during spring, which substantially limits our ability to predict ENSO events. By investigating nonlinear dynamic characteristics systems simulated a box model, we found that strong surface heating process in spring may contribute SPB regulating different coupling processes between ocean and atmosphere. Specifically, intensified springtime...
Abstract Katabatic flows are notoriously difficult to model for a variety of reasons. Notably, the assumptions underpinning Monin‐Obukhov similarity theory (MOST) inherently violated by sloping terrain, causing traditional flux‐gradient relations used in numerical weather prediction models break down. Focusing on turbulent momentum transport, we show significant flux divergence, further violating MOST assumptions, and that parameterizations fail even with local scaling katabatic flow. In...
Abstract The seasonal Predictability Barrier (PB) of Sea Surface Temperature Anomaly (SSTA) is characterized by a rapid loss prediction skills at particular season in dynamic models. Here, the connection between PB and inherent nonlinearity SSTA was investigated using statistical method known as Sample Entropy (SamEn). When SamEn value large, chaotic degree high. In Niño 3 3.4 regions, high spring; 4 region, it summer. This result consistent with occurrence these regions. month when peaked...
Abstract The El Niño-Southern Oscillation (ENSO) is a climate phenomenon characterized by the periodic fluctuation of Sea Surface Temperature (SST) anomaly in tropical Pacific Ocean, which has significant impact on global weather and patterns. However, predicting ENSO evolution several seasons advance challenging due to Spring Predictability Barrier (SPB) phenomenon, refers reduced accuracy forecasts during spring. By investigating nonlinear dynamic characteristics systems simulated box...
