Homeowners Handbook to Prepare for Natural Disasters
HOMEOWNERS HANDBOOK HANDBOOK HOMEOWNERS DELAWARE HOMEOWNERS TO PREPARE FOR FOR TO PREPARE HANDBOOK TO PREPARE FOR NATURAL HAZARDSNATURAL NATURAL HAZARDS TORNADOES COASTAL STORMS SECOND EDITION SECOND Delaware Sea Grant Delaware FLOODS 50% FPO 15-0319-579-5k ACKNOWLEDGMENTS This handbook was developed as a cooperative project among the Delaware Emergency Management Agency (DEMA), the Delaware Department of Natural Resources and Environmental Control (DNREC) and the Delaware Sea Grant College Program (DESG). A key priority of this project partnership is to increase the resiliency of coastal communities to natural hazards. One major component of strong communities is enhancing individual resilience and recognizing that adjustments to day-to- day living are necessary. This book is designed to promote individual resilience, thereby creating a fortified community.

Near Or Above Normal Atlantic Hurricane Season Predicted
Near or Above Normal Atlantic Hurricane Season Predicted NOAA’s Climate Prediction Center indicates climate conditions point to a near normal or above normal hurricane season in the Atlantic Basin this season. Their outlook calls for a 65 percent probability of an above normal season and a 25 percent probability of a near normal season. This means there is a 90 percent chance of a near or above normal season. The climate patterns expected during this year’s hurricane season have in past seasons produced a wide range of activity and have been associated with both near-normal and above-normal seasons. For 2008, the outlook indicates a 60 to 70 percent chance of 12 to 16 named storms, including 6 to 9 hurricanes and 2 to 5 major hurricanes (Category 3, 4 or 5 on the Saffir-Simpson Scale). An average season has 11 named storms, including six hurricanes for which two reach major status. The science behind the outlook is rooted in the analysis and prediction of current and future global climate patterns as compared to previous seasons with similar conditions. “The main factors influencing this year’s seasonal outlook are the continuing multi-decadal signal (the combination of ocean and atmospheric conditions that have spawned increased hurricane activity since 1995), and the anticipated lingering effects of La Niña,” said Gerry Bell, Ph.D., lead seasonal hurricane forecaster at NOAA’s Climate Prediction Center. “One of the expected oceanic conditions is a continuation since 1995 of warmer-than-normal temperatures in the eastern tropical Atlantic.” “The outlook is a general guide to the overall seasonal hurricane activity,” said retired Navy Vice Adm. -

THE PENNSYLVANIA STATE UNIVERSITY SCHREYER HONORS COLLEGE DEPARTMENT OF METEOROLOGY LOST IN THE FOG: AN ANALYSIS OF THE DISSEMINATION OF MISLEADING WEATHER INFORMATION ON SOCIAL MEDIA CHRISTINA M. REUILLE FALL 2015 A thesis submitted in partial fulfillment of the requirements for a baccalaureate degree in Meteorology with honors in Meteorology Reviewed and approved* by the following: Dr. Jon Nese Associate Head, Undergraduate Program in Meteorology Senior Lecturer in Meteorology Thesis Supervisor Dr. Yvette Richardson Associate Professor of Meteorology Honors Adviser * Signatures are on file in the Schreyer Honors College. i ABSTRACT The growing popularity of social media has created another avenue of weather communication. Social media can be a constant source of information, including weather information. However, a qualitative analysis of Facebook and Twitter shows that much of the information published confuses and scares consumers, making it ineffective communication that does more harm than good. Vague posts or posts that fail to tell the entire weather story contribute to the ineffective communication on social media platforms, especially on Twitter where posts are limited to 140 characters. By analyzing characteristics of these rogue posts, better social media practices can be deduced. Displaying credentials, explaining posts, and choosing words carefully will help make social media a more effective form of weather communication. ii TABLE OF CONTENTS LIST OF FIGURES .................................................................................................... -
A Review of Media Coverage of Climate Change and Global Warming in 2020 Special Issue 2020
A REVIEW OF MEDIA COVERAGE OF CLIMATE CHANGE AND GLOBAL WARMING IN 2020 SPECIAL ISSUE 2020 MeCCO monitors 120 sources (across newspapers, radio and TV) in 54 countries in seven different regions around the world. MeCCO assembles the data by accessing archives through the Lexis Nexis, Proquest and Factiva databases via the University of Colorado libraries. Media and Climate Change Observatory, University of Colorado Boulder http://mecco.colorado.edu Media and Climate Change Observatory, University of Colorado Boulder 1 MeCCO SPECIAL ISSUE 2020 A Review of Media Coverage of Climate Change and Global Warming in 2020 At the global level, 2020 media attention dropped 23% from 2019. Nonetheless, this level of coverage was still up 34% compared to 2018, 41% higher than 2017, 38% higher than 2016 and still 24% up from 2015. In fact, 2020 ranks second in terms of the amount of coverage of climate change or global warming (behind 2019) since our monitoring began 17 years ago in 2004. Canadian print media coverage – The Toronto Star, National Post and Globe and Mail – and United Kingdom (UK) print media coverage – The Daily Mail & Mail on Sunday, The Guardian & Observer, The Sun & Sunday Sun, The Telegraph & Sunday Telegraph, The Daily Mirror & Sunday Mirror, and The Times & Sunday Times – reached all-time highs in 2020. has been As the year 2020 has drawn to a close, new another vocabularies have pervaded the centers of critical year our consciousness: ‘flattening the curve’, in which systemic racism, ‘pods’, hydroxycholoroquine, 2020climate change and global warming fought ‘social distancing’, quarantines, ‘remote for media attention amid competing interests learning’, essential and front-line workers, in other stories, events and issues around the ‘superspreaders’, P.P.E., ‘doomscrolling’, and globe. -

Spring/Summer 1998 NSSL Briefings NSSL Briefings Volume 2 No. 3 Summer/Fall 1998 A newsletter about the employees and activities of the National Severe Storms Laboratory integrated research approach is the one being utilized by Erik Rasmussen and David Blanchard of NSSL, along with colleagues Jerry Straka and Paul Markowski of the University of Oklahoma. Thus far, a few important new findings have been made. We have found that boundaries, which are the leading edges of pools of cooler air left behind by thunderstorms, are prime locations for later tornado formation. Evidence suggests that the temperature contrast along these small-scale "fronts" supplies the air with horizontal rotation like a rolling pin. Then, when a mature storm moves across a boundary, the rotation is tilted upward into the storm's updraft so that the spin has the orientation of a top, while at the same time being stretched and intensified. This process imparts strong rotation to the lower levels of the storm updraft, which seems to be a necessary, but not sufficient, condition for tornado formation. Tornado formation itself seems to be strongly Near-ground fields in the tornadic region of the 2 June 1995 Dimmitt, Texas storm observed by VORTEX.

In tornadic supercells observed in VORTEX, this New findings on downdraft straddles two regions of opposite rotation: the developing mesocyclone, with its the origins of cyclonic, or counter-clockwise spin, and a region of anticyclonic, or clockwise spin, that spirals tornadoes from around the outside of the downdraft. -
Mesoscale and Stormscale Ingredients of Tornadic Supercells Producing Long-Track Tornadoes in the 2011 Alabama Super Outbreak
MESOSCALE AND STORMSCALE INGREDIENTS OF TORNADIC SUPERCELLS PRODUCING LONG-TRACK TORNADOES IN THE 2011 ALABAMA SUPER OUTBREAK BY SAMANTHA L. CHIU THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Atmospheric Science in the Graduate College of the University of Illinois at Urbana-Champaign, 2013 Urbana, Illinois Advisers: Professor Emeritus Robert B. Wilhelmson Dr. Brian F. Jewett ABSTRACT This study focuses on the environmental and stormscale dynamics of supercells that produce long-track tornadoes, with modeling emphasis on the central Alabama storms from April 27, 2011 - part of the 2011 Super Outbreak. While most of the 204 tornadoes produced on this day were weaker and short-lived, this outbreak produced 5 tornadoes in Alabama alone whose path-length exceeded 50 documented miles. The results of numerical simulations have been inspected for both environmental and stormscale contributions that make possible the formation and maintenance of such long–track tornadoes. A two-pronged approach has been undertaken, utilizing both ideal and case study simulations with the Weather Research and Forecasting [WRF] Model. Ideal simulations are designed to isolate the role of the local storm environment, such as instability and shear, to long-track tornadic storm structure. Properties of simulated soundings, for instance hodograph length and curvature, 0-1km storm relative helicity [SRH], 0-3km SRH and convective available potential energy [CAPE] properties are compared to idealized soundings described by Adlerman and Droegemeier (2005) in an effort to identify properties conducive to storms with non-cycling (sustained) mesocyclones. 200m horizontal grid spacing simulations have been initialized with the 18 UTC Birmingham/Alabaster, Alabama [KBMX] soundings, taken from an area directly hit by the day’s storms.
