  • Ex-Hurricane Ophelia 16 October 2017
    Ex-Hurricane Ophelia 16 October 2017 On 16 October 2017 ex-hurricane Ophelia brought very strong winds to western parts of the UK and Ireland. This date fell on the exact 30th anniversary of the Great Storm of 16 October 1987. Ex-hurricane Ophelia (named by the US National Hurricane Center) was the second storm of the 2017-2018 winter season, following Storm Aileen on 12 to 13 September. The strongest winds were around Irish Sea coasts, particularly west Wales, with gusts of 60 to 70 Kt or higher in exposed coastal locations. Impacts The most severe impacts were across the Republic of Ireland, where three people died from falling trees (still mostly in full leaf at this time of year). There was also significant disruption across western parts of the UK, with power cuts affecting thousands of homes and businesses in Wales and Northern Ireland, and damage reported to a stadium roof in Barrow, Cumbria. Flights from Manchester and Edinburgh to the Republic of Ireland and Northern Ireland were cancelled, and in Wales some roads and railway lines were closed. Ferry services between Wales and Ireland were also disrupted. Storm Ophelia brought heavy rain and very mild temperatures caused by a southerly airflow drawing air from the Iberian Peninsula. Weather data Ex-hurricane Ophelia moved on a northerly track to the west of Spain and then north along the west coast of Ireland, before sweeping north-eastwards across Scotland. The sequence of analysis charts from 12 UTC 15 to 12 UTC 17 October shows Ophelia approaching and tracking across Ireland and Scotland.

  • The Effects of Diabatic Heating on Upper
    THE EFFECTS OF DIABATIC HEATING ON UPPER- TROPOSPHERIC ANTICYCLOGENESIS by Ross A. Lazear A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science (Atmospheric and Oceanic Sciences) at the UNIVERSITY OF WISCONSIN - MADISON 2007 i Abstract The role of diabatic heating in the development and maintenance of persistent, upper- tropospheric, large-scale anticyclonic anomalies in the subtropics (subtropical gyres) and middle latitudes (blocking highs) is investigated from the perspective of potential vorticity (PV) non-conservation. The low PV within blocking anticyclones is related to condensational heating within strengthening upstream synoptic-scale systems. Additionally, the associated convective outflow from tropical cyclones (TCs) is shown to build upper- tropospheric, subtropical anticyclones. Not only do both of these large-scale flow phenomena have an impact on the structure and dynamics of neighboring weather systems, and consequently the day-to-day weather, the very persistence of these anticyclones means that they have a profound influence on the seasonal climate of the regions in which they exist. A blocking index based on the meridional reversal of potential temperature on the dynamic tropopause is used to identify cases of wintertime blocking in the North Atlantic from 2000-2007. Two specific cases of blocking are analyzed, one event from February 1983, and another identified using the index, from January 2007. Parallel numerical simulations of these blocking events, differing only in one simulation’s neglect of the effects of latent heating of condensation (a “fake dry” run), illustrate the importance of latent heating in the amplification and wave-breaking of both blocking events.

  • The Extratropical Transition of Hurricane Ophelia (2017) As Diagnosed with a Generalized Omega Equation and Vorticity Equation
    The extratropical transition of Hurricane Ophelia (2017) as diagnosed with a generalized omega equation and vorticity equation 1 1 1 1 Mika Rantanen ,​ Jouni Räisänen ,​ Victoria A. Sinclair ​ and Heikki Järvinen ​ ​ ​ ​ 1 I​ nstitute for Atmospheric and Earth System Research, University of Helsinki, Helsinki, Finland Hurricane Ophelia was a category 3 hurricane which underwent an extratropical transition and made landfall in Europe as an exceptionally strong post-tropical cyclone in October 2017. In Ireland, for instance, Ophelia was the worst storm in 50 years and resulted in significant damage and loss of life. In this study, the different physical processes affecting Ophelia’s transformation from a hurricane to a mid-latitude cyclone are studied. For this purpose, we have developed software which uses OpenIFS model output and a system consisting of a generalized omega equation and vorticity equation. By using these two equations, the atmospheric vertical motion and vorticity tendency are separated into the contributions from different physical processes: vorticity advection, thermal advection, friction, diabatic heating, and the imbalance between the temperature and vorticity tendencies. Vorticity advection, which is often considered an important forcing for the development of mid-latitude cyclones, is shown to play a small role in the re-intensification of Ophelia as an extratropical storm. This is because the effects of divergent and non-divergent components of vorticity advection mainly cancelled each other out, resulting in a net effect close to zero. However, our results show that diabatic heating was the dominate forcing in both the tropical and extratropical phases of Ophelia. Furthermore, we calculated in more detail the diabatic heating contributions from different model parameterizations.

  • A Complex Aerosol Transport Event Over Europe During
    A complex aerosol transport event over Europe during the 2017 Storm Ophelia in CAMS forecast systems: analysis and evaluation Dimitris Akritidis1, Eleni Katragkou1, Aristeidis K. Georgoulias1, Prodromos Zanis1, Stergios Kartsios1, Johannes Flemming2, Antje Inness2, John Douros3, and Henk Eskes3 1Department of Meteorology and Climatology, School of Geology, Aristotle University of Thessaloniki, Thessaloniki, Greece 2European Centre for Medium-Range Weather Forecasts (ECMWF), Reading, UK 3Royal Netherlands Meteorological Institute (KNMI), De Bilt, the Netherlands Correspondence: D. Akritidis ([email protected]) Abstract. In mid-October 2017 Storm Ophelia crossed over western coastal Europe, inducing the combined transport of Sa- haran dust and Iberian biomass burning aerosols over several European areas. In this study we assess the performance of the Copernicus Atmosphere Monitoring Service (CAMS) forecast systems during this complex aerosol transport event, and the po- tential benefits that data assimilation and regional models could bring. To this end, CAMS global and regional forecast data are 5 analyzed and compared against observations from passive (MODIS: Moderate resolution Imaging Spectroradiometer aboard Terra and Aqua) and active (CALIOP/CALIPSO: Cloud-Aerosol Lidar with Orthogonal Polarization aboard Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations) satellite sensors, and ground-based measurements (EMEP: European Monitoring and Evaluation Programme). The analysis of CAMS global forecast indicates that dust and smoke aerosols, dis- cretely located on the warm and cold front of Ophelia, respectively, are affecting the aerosol atmospheric composition over 10 Europe during the passage of the Storm. The observed MODIS Aerosol Optical Depth (AOD) values are satisfactorily repro- duced by CAMS global forecast system, with a correlation coefficient of 0.77 and a fractional gross error (FGE) of 0.4.

  • I. INTRODUCTION As Part of the Beaufort
    PAMLICO SOUND REGIONAL HAZARD MITIGATION PLAN SECTION 3. HAZARD IDENTIFICATION AND ANALYSIS I. INTRODUCTION As part of the Beaufort, Carteret, Craven, Hyde, and Pamlico counties hazard mitigation efforts and the preparation of this plan, the five-county region will need to decide on which specific hazards it should focus its attention and resources. To plan for hazards and to reduce losses, the Pamlico Sound Region needs to know: 1) the type of natural hazards that threaten the region, 2) the characteristics of each hazard, 3) the likelihood of occurrence (or probability) of each hazard, 4) the magnitude of the potential hazards, and 5) the possible impacts of the hazards on the community. The following section identifies each hazard that poses an elevated threat to the counties and municipalities located within the Pamlico Sound Region. A rating system that evaluates the potential for occurrence for each identified threat is provided (see Table 39). The following natural hazards were determined to be of concern for the five-county region: 1. Hurricanes 2. Nor’easters 3. Flooding 4. Severe Winter Storms 5. Thunderstorms/Windstorms 6. Tornados 7. Wildfire 8. Earthquakes 9. Dam/Levee Failure 10. Tsunamis 11. Droughts/Heat Waves 12. Coastal Hazards A detailed explanation of these hazards and how they have impacted the five-county region is provided on the following pages. The weather history summaries provided throughout this discussion have been compiled from the National Oceanic and Atmospheric Administration (NOAA) as provided through the National Climatic Data Center (NCDC). The NCDC compiles monthly reports that track weather events and any financial or life loss associated with a given occurrence.

  • Tropical Cyclone Report Hurricane Ophelia 6-17 September 2005
    Tropical Cyclone Report Hurricane Ophelia 6-17 September 2005 Jack Beven and Hugh D. Cobb, III National Hurricane Center 24 January 2006 Updated track near Nova Scotia 14 June 2006 Hurricane Ophelia was a category 1 hurricane on the Saffir-Simpson Hurricane Scale that brushed the North Carolina Outer Banks, its center staying just offshore from that coast. The storm’s erratic and slow movement in the vicinity of the North Carolina coastline was similar to Hurricanes Bonnie in August 1998 and Dennis in August 1999. a. Synoptic History Ophelia formed from a non-tropical weather system. A cold front moved off the eastern coast of the United States on 1 September. The front moved southeastward and became part of an elongated trough of low pressure that extended from Tropical Depression Lee east of Bermuda to near the Florida Peninsula. Two areas of low pressure formed in the trough on 4 September. The eastern low, south of Bermuda, eventually became Hurricane Nate. The western low, near the Bahamas, became Ophelia. The pre-Ophelia low initially drifted southward. It began a northward drift on 5 September while the associated shower activity became better organized. Based on satellite, surface, and radar observations, it is estimated the low became a tropical depression near 0600 UTC 6 September between Andros and Grand Bahama Islands. 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 1. The depression moved generally northward, with the broad circulation center crossing Grand Bahama about 1600 UTC 6 September.

  • 2017 North Atlantic Hurricane Season Review
    2017 North Atlantic Hurricane Season Review RMS REPORT Executive Summary THE 2017 NORTH ATLANTIC HURRICANE SEASON will be remembered as one of the most active, damaging, and costliest seasons on record. The 2017 season saw 17 named storms, with 10 of these storms (Franklin through Ophelia) reaching hurricane strength and occurring consecutively within a hyperactive period between August and October. The season will be remembered for its six major hurricanes and specifically for the impacts of three of these storms: Harvey, Irma, and Maria. Hurricane Harvey, the first U.S. major hurricane (Category 3 or greater on the Saffir-Simpson Hurricane Wind Scale) to make landfall since Hurricane Wilma in 2005, made landfall near Rockport, Texas, as a Category 4 storm in late August, thus ending the contiguous U.S. major hurricane landfall drought at 4,323 days. Harvey brought record-breaking rainfall to southeast Texas that resulted in widespread catastrophic and unprecedented inland flooding across the Houston metropolitan area, damaging more than 300,000 structures. The RMS best estimate is that the insured loss from Hurricane Harvey will likely be between US$25 and US$35 billion. This estimate represents the insured loss associated with wind, storm surge, and inland flood damage across Texas and Louisiana. Florida saw its first Category 4 hurricane landfall since 2004 when Hurricane Irma made landfall over the Florida Keys in mid-September. The system later came ashore near Naples, Florida as a Category 3 storm, causing widespread wind damage and flooding across the state. Before impacting Florida, Irma tracked through the Caribbean as a Category 5 hurricane and caused extensive devastation on many islands, ultimately ranking as the strongest hurricane on record to impact the Leeward Islands.

Introduction Hurricanes and tropical storms that form in the tropical Atlantic, usually from August to October, which is the peak of the Atlantic hurricane season, are occasionally picked up by the North Atlantic jet stream and swept north-eastwards towards Europe. By the time they reach Ireland, they are usually no longer classified as hurricanes, having transi- tioned into what are known as post or extra-tropical storms but can be quite powerful and damaging. Extra-Tropical Storm Ophelia (also known as Storm Ophelia) was not the only tropical system to affect Ireland in the 2017-2018 windstorm season. The remnants of Hurricane Gert and Nate had already brought heavy rainfall and flooding to some parts of Ireland in August and October but little in the way of wind. Ophelia is the farthest east Major Hurricane (Category 3 or higher) on record in the Atlantic Basin. It made landfall over Ireland as an extra-tropical storm on the morning of the 16th October 2017 resulting in observed wind speeds of up to 156 km/h, in a (3-second mean) gust, at Roche’s Point station, County Cork.
