This study investigates the impact of abnormally moist soil conditions across the southern Great Plains upon the overland reintensification of North Atlantic Tropical Cyclone Erin (2007). This is tested by analyzing the contributions of three soil moisture–related signals—a seasonal signal, an along-track rainfall signal, and an early postlandfall rainfall signal—to the intensity of the vortex....

Nitrous acid (HONO) photolysis constitutes a primary source of OH in the early morning, which leads to changes in model gas-phase and particulate matter concentrations. However, state-of-the-art models of chemical mechanisms share a common representation of gas-phase chemistry leading to HONO that fails in reproducing the observed profiles. Hence, there is a growing interest in improving the de...

Forecasts generated with 1 and 4 km grid spacing using the WRF-ARW model (ARW1 and ARW4, respectively) during the 2009-2011 NOAA Hazadous Weather Testbed Spring Experiments by the Center for Analysis and Prediction of Storms are compared and verified using object-based measures, including average values of object attributes, the Object-based Threat Score (OTS) and the Median of Maximum Interest...

The CALIOPE-EU high-resolution air quality modeling system, namely WRF-ARW/HERMES-EMEP/CMAQ/ BSC-DREAM8b, is developed and applied to Europe (12 km 12 km, 1 h). The model performances are tested in terms of air quality levels and dynamics reproducibility on a yearly basis. The present work describes a quantitative evaluation of gas phase species (O3, NO2 and SO2) and particulate matter (PM2.5 a...

Negation is known to vary considerably in both form and morphosyntactic function among the languages of the Arawak family (Aikhenvald 1999: 96), with even closely-related languages sometimes exhibiting negation elements with starkly different forms and functions. The purpose of this chapter is to present a typological overview of negation in Arawak languages and to develop a preliminary compara...

The model initialization with high-resolution SAR wind data provided by the Sentinel-1 mission and its impact on meteorological WRF-ARW simulations is discussed. activity performed within Horizon 2020 CEASELESS project, focusing one of target areas, northern Adriatic Sea (northern-central Mediterranean). ingested into LAPS, a numerical system developed at NOAA, specifically designed for analysi...

This paper describes the development of Fiber Optic Gyroscope (FOG) for Space applications at LEOS. The sensor has all solid-state optical devices for the precise measurements of mechanical rotation. The basic phenomenon underlying optical rotation sensing is known as the Sagnac effect. In the Sagnac effect two identical light beams traveling in opposite directions around a closed loop path exp...
