While the typhoon was over the open ocean and moved north-northwestward in speed of 15 km/h, its eyewall was not well organized. The rainbands, separated from the inner core region and located at the first and second quadrants relative to the moving direction of typhoon, were embedded with active con- vections. The vertical cross sections along the radial showed that the outer rainbands tilted outward and were more intense than the inner ones. As the typhoon system gradually propagated to the offshore area near the southeast coast of Taiwan, the semi-elliptic eyewall was built up at the second and third quad- rants.

    Revisiting disasters in Cabo Verde: a historical review of droughts and food insecurity events to enable future climate resilience CARLOS GERMANO FERREIRA COSTA (*) 1. INTRODUCTION Climate change is an urgent issue, primarily understood as a collective problem that demands individual actions. As a fact, the changing climate has a profound impact and significance for global sustainability and na- tional development policy in short-, medium- and long-terms (Ferreira Costa, 2016). Climate change calls for new paths to sustainable develop- ment that take into account complex interplays between climate, tech- nological, social, and ecological systems as a process, not as an outcome (Manyena, 2006; Olhoff and Schaer, 2010; Denton et al., 2014). These approaches should integrate current and evolving understandings of cli- mate change impact and consequences and conventional and alterna- tive development pathways to meet the goals of sustainable development (Fleurbaey et al., 2014; IPCC, 2014; 2014a). Billions of people, particularly those in developing countries, already face shortages of water and food, and more significant risks to health, assets, forced migration, and life as a result of climate change, and cli- mate-driven conflict (Kummu et al., 2016; Caniato et al., 2017; FAO/ (*) Ministerio de Ciencia, Tecnología, Innovación y Comunicaciones de Brasil (MCTIC), Comisión Interminis- terial de Cambio Global del Clima - investigador/consultor técnico Revista Española de Estudios Agrosociales y Pesqueros, n.º 255, 2020 (47-76).

    Hurricane Fred fades with a satellite exclamation point 14 September 2009 September 11) and Fred is no longer classifiable using the Dvorak technique. The lack of deep convection also means that Fred is no longer a tropical cyclone and is now declared a remnant low pressure area." The NHC used data from NASA's QuikScat instrument (on the SeaWinds satellite) to determine that Fred's circulation had weakened to that point. As of this morning, Monday, September 14, the NHC said that Fred's remnants may continue to produce intermittent shower and thunderstorm activity as it moves west-northwestward at 10 to 15 mph over the next couple of days.

    High-resolution Hurricane Forecasts Chris Davis, Wei Wang, Steven Cavallo, James Done, Jimy Dudhia, Sherrie Fredrick, John Michalakes, Ginger Caldwell, and Tom Engel National Center for Atmospheric Research1 Boulder, Colorado Ryan Torn University at Albany, SUNY Albany, New York Submitted to Computing in Science and Engineering Revised, April, 2010 Corresponding Author: Christopher A. Davis P.O. Box 3000 Boulder, CO 80307 [email protected] Phone: 303-497-8990 Fax: 303-497-8181 1 The National Center for Atmospheric Research is sponsored by the National Science Foundation. 2 Abstract The authors discuss the challenges of predicting hurricanes using dynamic numerical models of the atmosphere-ocean system. The performance of particular model is investigated for a large sample of Atlantic tropical cyclones from the 2005, 2007 and 2009 hurricane seasons. The model, derived from the Weather Research and Forecasting (WRF) model, is capable of resolving the deep convective motions within a hurricane and the eye and eye wall of the storm. The use of finer resolution leads to demonstrably improved predictions of storm intensity compared with predictions from coarser resolution models. Possible future real-time applications of this model in a high-performance computing environment are discussed using hurricane Bill (2009) as an example. These applications are well suited to massively parallel architectures. 3 1. Introduction The prediction of hurricane intensity remains a daunting challenge even after four decades of research. The intrinsic difficulties lay in the vast range of spatial and temporal scales of atmospheric motions that affect tropical cyclone intensity. The range of spatial scales is literally millimeters to 1000 kilometers or more.

Hurricane Fred 2 Hurricane Fred 30 AUGUST – 6 SEPTEMBER 2015 SYNOPTIC HISTORY Fred formed from a tropical wave that emerged from the west coast of Africa on 29 August. Unlike most tropical waves, Fred’s precursor began to develop almost immediately upon reaching the Atlantic, and a low pressure area formed just west of the coast of Guinea later that day. The center of the low re-formed northward late on 29 August, and it is estimated that a tropical depression developed near 0000 UTC 30 August about 260 n mi west-northwest of Conakry, Guinea. The “best track” chart of the tropical cyclone’s path is given in Fig. 1, with the wind and pressure histories shown in Figs. 2 and 3, respectively. The best track positions and intensities are listed in Table 11. The depression moved quickly on an aclimatological northwestward track after genesis, steered by a weakness in the subtropical ridge north of Cabo Verde. Microwave data showed that the system developed a well-defined inner core during or just after genesis (Fig. 4), and this, in combination with warm sea surface temperatures and light vertical wind shear, allowed a rapid strengthening that was also not normal for this area.

Between June 1 and November 30, 2009, only nine named storms developed in the Atlantic basin, three of which became hurricanes. These are the lowest totals in each category since 1997, according to the Insurance Information Institute (I.I.I.). “The 2009 season is a welcome respite from 2008, when hurricanes Gustav and Ike disrupted hundreds of thousands of lives in Louisiana and Texas, and caused $14.65 billion in insured losses,” said Dr. Robert Hartwig, an economist and president of the I.I.I. “Profits in an industry like insurance must be seen over the long term. A single hurricane, or a string of large losses, can wipe out insurer profits from previous years, or even decades. And insurers must be prepared to pay for these losses, irrespective of the current economic conditions.” The nine named storms, according to a Colorado State University analysis of the 2009 Atlantic hurricane season, were, in chronological order: Tropical Storm Ana (Aug. 15-16) Hurricane Bill (Aug.
