2007 Atmospheric Research Technical Highlights NASA/TM—2008–214160 Laboratory for Atmospheres 2007 Technical Highlights May 2008 Cover Caption: Field campaigns are a central element in the research carried out by Laboratory scientists. During 2007, the Tropical Composition, Cloud, and Climate Coupling (TC4) mission was the major effort. The cover photo is a group picture of participants in the DC8 portion of the mission. Over 350 people from NASA, NOAA, NCAR, universities, Costa Rica, and Panama directly participated in TC4. NASA’s DC-8 “Flying Laboratory” carried a complement of 26 instruments including upward and downward pointing lidars (ozone, water vapor, and aerosols) and radiometers, as well as instruments for in situ measurements of gases, and cloud and aerosol particles. The DC-8 was key for Aura validation objectives as it was able to underfly the afternoon Aura overpass, which was not possible for other TC4 aircraft, the ER-2 and WB-57, because of typical afternoon weather conditions at the airfield.

I thank you for your interest. We publish this report each year to describe our research and to summarize our accomplishments. This document is intended for a broad audience. Our readers include colleagues within NASA, scientists outside the agency, science graduate students, and members of the general public. Inside are descriptions of our organization and facilities, our major activities and science highlights, and our education and outreach accomplishments for calendar year 2007. The Laboratory’s approximately 230 scientists, technologists, and administrative personnel are part of the Earth Sciences Division in the Sciences and Exploration Directorate of the NASA Goddard Space Flight Center. The Laboratory for Atmospheres is continuing our mission of advancing knowledge and understanding of the Earth’s atmosphere. Laboratory scientists continued having a productive year organizing and participating in international field campaigns, developing and refining instruments, analyzing data, expanding data sets, and improving models. The Aura spacecraft, launched in July 2004 is an important component of the Lab’s science activities through validation campaigns and data analysis and modeling. These efforts are helping us better understand our home planet’s environment, and are increasing our knowledge of the complex chemistry of the atmosphere. Several noteworthy events took place during 2007. Field campaigns contributing to Aura validation efforts in 2007 began with the SAUNA II campaign in Sodankylä, Finland during February. This year’s largest mission, carried out in the summer of 2007, was the Tropical Composition, Cloud, and Climate Coupling (TC4) campaign. This effort involved personnel from all three of the Laboratory’s branches, as well as investigators from other NASA Centers, NOAA, NCAR, universities, Costa Rica, and Panama. Other campaigns were the Cloud and Land Surface Interaction Campaign (CLASIC), and the Water Vapor Validation Experiment-Satellite/Sondes (WAVES_2007) at the Howard University Research Campus in Beltsville, MD. These, and several other field campaigns in which Laboratory members participated are described in detail in Section 4, Major Activities. WAVES_2007, which involved students from Howard University, as well as Laboratory members, is further discussed in Section 6, Education and Outreach. As in previous years, Laboratory scientists garnered many top professional honors. Bob Adler (613) received the William Nordberg Award for his outstanding long-term contributions to precipitation science, in particular his dedicated efforts as TRMM Project Scientist in ensuring the phenomenal success of that mission. Tom McGee (613.3) received the Alan Berman Research Publication Award from The Department of the Navy and Naval Research Laboratory (NRL) for technical merit and clarity. Anne Douglass (613.3) and William Lau (613) were honored as AGU Fellows at the AGU Honors Ceremony held in conjunction with the spring AGU Joint Assembly, Acapulco, Mexico. These, and numerous other awards received by Laboratory members, are described in Section 5.6 of this report. We continued the very successful Laboratory Monthly Seminar Series, which focused on precipitation, clouds, aerosol and their physical/chemical linkages; details of the series can be found on our Web site. The year 2007 was also a time to bid farewell to Jean Howard, our Laboratory’s secretary for more than 3 years, and to retirees Andy Negri, and Chuck Cote. Andy had a distinguished career spanning 28 years as a Meteorologist in the Mesoscale Atmospheric Processes Branch. Chuck retired after 45 years of Government service. He served as the Associate Chief of our Laboratory for more than 20 years. I am pleased to welcome Ralph Kahn to our Laboratory staff. Ralph is joining the Climate and Radiation Branch where he will continue his work on aerosols carried out during his tenure at JPL. He is also active in educational activities and maintains an educational Web site described in Section 6 of this report. This report is being published in two media: a printed version, and an electronic version on our Laboratory for Atmospheres Web site, http://atmospheres.gsfc.nasa.gov. It continues to be redesigned to be more useful for our scientists, colleagues, and the public. We welcome comments on this 2007 report and on the material displayed on our Web site.

    PERILS PUTS INITIAL LOSS ESTIMATE FOR EXTRATROPICAL CYCLONE XAVIER AT EUR 291M Zurich, 16 November 2017 – PERILS, the independent Zurich-based organisation providing industry-wide catastrophe insurance data, has today disclosed its initial loss estimate for Extratropical Cyclone Xavier, which primarily affected Germany on 5 October 2017. PERILS’ initial estimate of the insured property market loss for Xavier, based on loss data from affected insurers collected post-event, is EUR 291 million. In line with the PERILS reporting schedule, an updated estimate of the Xavier market loss will be made available on 5 January 2018, three months after the event start date. Xavier was a very fast-moving and violent storm which caused the deaths of seven people in Germany. It occurred very early in the European winter storm season which meant that many trees were still heavy with leaves and therefore were more prone to being blown over than had the same winds occurred during the winter months. Damaging gusts occurred along a narrow corridor approximately 250 km wide which ran ENE-WSW from Hamburg to Berlin and affected the states of Hamburg, Lower Saxony, Saxony-Anhalt, Brandenburg and Berlin. The duration of the intense winds experienced over northern and eastern Germany was approximately 14 hours, reflecting the extraordinarily rapid passage of Xavier. Extratropical Cyclone Xavier, maximum gust values in km/h: Xavier struck Germany on 5 October 2017 with violent gusts affecting a narrow corridor from Hamburg to Berlin. Xavier caused the deaths of seven people in Germany.

  • Spatial and Temporal Analysis of Extreme Sea Level and Storm Surge Events Around the Coastline of the UK 15 2016 Received: July 1 1 2 2 3 1 2 Ivan D
    www.nature.com/scientificdata OPEN Analysis: Spatial and temporal analysis of extreme sea level and storm surge events around the coastline of the UK 15 2016 Received: July 1 1 2 2 3 1 2 Ivan D. Haigh , Matthew P. Wadey , , Thomas Wahl , , Ozgun Ozsoy , Robert J. Nicholls , Accepted: 3 November 2016 4 4 5 Jennifer M. Brown , Kevin Horsburgh & Ben Gouldby Published: 6 December 2016 In this paper we analyse the spatial footprint and temporal clustering of extreme sea level and skew surge events around the UK coast over the last 100 years (1915–2014). The vast majority of the extreme sea level events are generated by moderate, rather than extreme skew surges, combined with spring astronomical high tides. We distinguish four broad categories of spatial footprints of events and the distinct storm tracks that generated them. There have been rare events when extreme levels have occurred along two unconnected coastal regions during the same storm. The events that occur in closest succession (o4 days) typically impact different stretches of coastline. The spring/neap tidal cycle prevents successive extreme sea level events from happening within 4–8 days. Finally, the 2013/14 season was highly unusual in the context of the last 100 years from an extreme sea level perspective. 1 Ocean and Earth Science, National Oceanography Centre, University of Southampton, European Way, 2 Southampton SO14 3ZH, UK.

By using a 39-station UK surface 23 observation network, coupled with in-depth analysis of the causes of extreme gusts during the 24 period 2008-2014, we show that larger scale features (warm and cold conveyer belts) are 25 most commonly associated with the top 1% of UK gusts but smaller scale features generate 26 the most extreme winds. The cold conveyor belt is far more destructive when joining the 27 momentum of the ETC, rather than earlier in its trajectory, ahead of the approaching warm 28 front.

  • COASTAL STORMS/HURRICANES Description
    SECTION I – COASTAL STORMS/HURRICANES Description: Warm water heats the air, and it rises as it nears the center. The ocean feeds warmth and moisture into the storm, providing energy that causes the warm air in the center to rise faster. It condenses high in the atmosphere, creating thunderstorms. (National Weather Service). Coastal storms can cause increases in tidal elevations (called storm surge), wind speed and erosion. Coastal storms produce gale force winds and heavy precipitation. The storms can last for several days and can be very large – 1,000-mile-wide storms are not uncommon. A hurricane is a category of tropical storm of wind speeds greater than 74 or more miles per hour. Hurricanes develop over warm waters and are caused by the atmospheric instability created by the collision of warm air with cooler air. Hurricane winds blow in a large spiral around a calm center called the eye, which can be 20-30 miles wide. When a hurricane nears land, it may bring torrential rains, high winds, storm surges, coastal flooding, inland flooding, and sometimes, tornadoes. A single hurricane can last for more than two weeks over water and can extend outward 400 miles. The hurricane season for the Atlantic coast is June 1 to November 30. On average, five hurricanes strike the United States every year. In a two-year period, an average of three significant (category 3 or higher) hurricanes will strike the United States. Some hurricanes are characterized primarily by water – a rainy or wet hurricane – while others are primarily characterized by wind - a windy or dry hurricane.

  • Windstorms in Northwest Europe in Late 2013
    from Newsletter Number 139 – Spring 2014 METEOROLOGY Windstorms in northwest Europe in late 2013 doi:10.21957/fn6uazeu T. Hewson et al. Windstorms in northwest Europe in late 2013 This article appeared in the Meteorology section of ECMWF Newsletter No. 139 – Spring 2014, pp. 22–28. Windstorms in northwest Europe in late 2013 Tim Hewson, Linus Magnusson, Oyvind Breivik, Fernando Prates, Ivan Tsonevsky, Hans (J.W.) de Vries The winter period of 2013/14 has been very active in terms of windstorms affecting northwest Europe. This article provides a short summary of two such storms, from 28 October (Christian) and 5 December (Xaver), and the handling thereof by the ECMWF IFS (Integrated Forecasting System). It is shown that for both storms IFS output provided an indication of high winds 5 to 6 days in advance. This is important because a key component of ECMWF’s strategy is to provide Member States’ National Meteorological Services with reliable forecasts of severe weather across the medium range. Figure 1 shows a model-based estimate of areas where the 5-year return period of 24-hour maximum wind gust was exceeded for Christian and for Xaver. Here we have used ERA-Interim forecasts as a proxy for observations, with red squares denoting those grid points where maximum wind gust in the short-range (0–24 hour) forecast from ERA-Interim exceeded the 5-year return period value. Return period values were first estimated by fitting the generalised extreme value distribution to a 20-year block of annual maximum wind gust (again using 0–24 hour ERA-Interim forecasts).
