A set of nine synoptic-flow cases, incorporating Omega dropwindsonde observations for six tropical storms and hurricanes, is used to deduce the three-dimensional distribution of potential vorticity (PV) that contributed to the deep-layer mean (DLM) wind that steered the cyclones. A piecewise inver...

On Monday, the National Hurricane Center designated a disturbance in the Gulf of Mexico as apotential tropical cyclonethat has yet to be named, with tropical storm warnings in effect along the northeastern coast of Mexico and in southern Texas. Winds in excess of 39 MPH are expected over a l...
(1982), defines six stability classifications: A (Extremely unstable) through F (Moderately stable). Class D is for neutral conditions. The classifications are defined by ranges of observations of surface wind speed and solar insolation during daytime hours, or surface wind speed and cloud cover ...
Under tropical cyclone conditions, spray droplets contribute to the heat and momentum transfer between the ocean and atmosphere15,16,17,18. Kepert et al.19and Peng and Richter20noted the following fundamental issues that relate to spray effects: the sea spray generation function, the feedback by...
Fig. 5: Error quantification of coastal maximum elevations derived from six global DEMs (CoastDEM, MERIT, SRTM30, ASTER, TandemX90, and AW3D30), relative to LIDAR data for two regions in France and the Netherlands. a, b, respectively, show the maps of the local elevation data and the ...
Typhoons and hurricanes are the most powerful weather event on Earth. One of the ways NASA researches tropical cyclones is using infrared data that provide temperature information. Launched on May 4, 2002, the AIRS instrument is one of six instruments flying on board NASA's Aqua satellite....
Ocean-surface winds from SMOS (in knots) under Cyclone Idai on 13 March 2019. The wind radii estimates in each geographical storm quadrant are illustrated by black segments as deduced from SMOS data and by grey segments for the Automated Tropical Cyclone Forecast system. These line segments are...
This was witnessed in Samoa where a severe armyworm epidemic was reported six months after Cyclone Val in 1991 (Liyanage and Misipati 1993; Carmichael et al. 2008). Future climate warming is likely to change the distribution of lepidopteran insects with poleward shifts in geographical ranges (...
