    Property Risk Consulting Guidelines PRC.15.1.1 A Publication of AXA XL Risk Consulting WINDSTORMS INTRODUCTION A variety of windstorms occur throughout the world on a frequent basis. Although most winds are related to exchanges of energy (heat) between different air masses, there are a number of weather mechanisms that are involved in wind generation. These depend on latitude, altitude, topography and other factors. The different mechanisms produce windstorms with various characteristics. Some affect wide geographical areas, while others are local in nature. Some storms produce cooling effects, whereas others rapidly increase the ambient temperatures in affected areas. Tropical cyclones born over the oceans, tornadoes in the mid-west and the Santa Ana winds of Southern California are examples of widely different windstorms. The following is a short description of some of the more prevalent wind phenomena. A glossary of terms associated with windstorms is provided in PRC.15.1.1.A. The Beaufort Wind Scale, the Saffir/Simpson Hurricane Scale, the Australian Bureau of Meteorology Cyclone Severity Scale and the Fugita Tornado Scale are also provided in PRC.15.1.1.A. Types Of Windstorms Local Windstorms A variety of wind conditions are brought about by local factors, some of which can generate relatively high wind conditions. While they do not have the extreme high winds of tropical cyclones and tornadoes, they can cause considerable property damage. Many of these local conditions tend to be seasonal. Cold weather storms along the East coast are known as Nor’easters or Northeasters. While their winds are usually less than hurricane velocity, they may create as much or more damage.

    ESSENTIALS OF METEOROLOGY (7th ed.) GLOSSARY Chapter 1 Aerosols Tiny suspended solid particles (dust, smoke, etc.) or liquid droplets that enter the atmosphere from either natural or human (anthropogenic) sources, such as the burning of fossil fuels. Sulfur-containing fossil fuels, such as coal, produce sulfate aerosols. Air density The ratio of the mass of a substance to the volume occupied by it. Air density is usually expressed as g/cm3 or kg/m3. Also See Density. Air pressure The pressure exerted by the mass of air above a given point, usually expressed in millibars (mb), inches of (atmospheric mercury (Hg) or in hectopascals (hPa). pressure) Atmosphere The envelope of gases that surround a planet and are held to it by the planet's gravitational attraction. The earth's atmosphere is mainly nitrogen and oxygen. Carbon dioxide (CO2) A colorless, odorless gas whose concentration is about 0.039 percent (390 ppm) in a volume of air near sea level. It is a selective absorber of infrared radiation and, consequently, it is important in the earth's atmospheric greenhouse effect. Solid CO2 is called dry ice. Climate The accumulation of daily and seasonal weather events over a long period of time. Front The transition zone between two distinct air masses. Hurricane A tropical cyclone having winds in excess of 64 knots (74 mi/hr). Ionosphere An electrified region of the upper atmosphere where fairly large concentrations of ions and free electrons exist. Lapse rate The rate at which an atmospheric variable (usually temperature) decreases with height. (See Environmental lapse rate.)

  • Plans and Prospects for Coastal Flooding in Four Communities Affected by Sandy
    APRIL 2017 W O N G - P A R O D I E T A L . 183 Plans and Prospects for Coastal Flooding in Four Communities Affected by Sandy GABRIELLE WONG-PARODI Department of Engineering and Public Policy, Carnegie Mellon University, Pittsburgh, Pennsylvania BARUCH FISCHHOFF Department of Engineering and Public Policy, and Institute for Politics and Strategy, Carnegie Mellon University, Pittsburgh, Pennsylvania BEN STRAUSS Climate Central, Princeton, New Jersey (Manuscript received 4 April 2016, in final form 1 December 2016) ABSTRACT The risk of coastal flooding is increasing due to more frequent intense storm events, rising sea levels, and more people living in flood-prone areas. Although private adaptation measures can reduce damage and risk, most people living in risk-prone areas take only a fraction of those measures voluntarily. The present study examines relationships among individuals’ beliefs and actions regarding flood-related risks based on in-depth interviews and structured surveys in communities deeply affected by Superstorm Sandy. The authors find that residents recognize the risk of coastal flooding and expect it to increase, although they appear to un- derestimate by how much. Although interview participants typically cited climate change as affecting the risks that they face, survey respondents’ acceptance of climate change was unrelated to their willingness to tolerate coastal flooding risks, their beliefs about the effectiveness of community-level mitigation measures, or their willingness to take individual actions. Respondents who reported greater social support also reported both greater tolerance for flood risks and greater confidence in community adaptation measures, suggesting an important, but complex role of personal connections in collective resilience—both keeping people in place and helping them to survive there.

  • Coastal Hazards & Flood Mapping – a Visual Guide
    COASTAL HAZARDS & FLOOD MAPPING A VISUAL GUIDE Coastal communities are special places and home to important resources. But what makes them so distinctive is also what makes them at high risk for floods. Floods are the nation’s costliest natural disasters, and coastal communities face many flood risks. These include storm surges, powerful waves, and erosion — all of which can cause extensive damage to homes, businesses, and public spaces. When a coastal storm approaches, community leaders and members of the media may use technical terms to describe storm-related risks. This visual guide explains these terms and how they relate to information shown on flood maps.

  • Combatting Climate Change the Drought We All Recently Experienced
    Board Director Guest Column Director Linda LeZotte, District 4 Combatting climate change The drought we all recently experienced in California was not only the longest dry spell in history, it was also a forewarning of the extremes that await with a changing climate. Five years of severe drought morphed into deluge shortly after with record rainfall in northern California. As the county’s water resource agency, the Santa Clara Valley Water District works to respond to the looming impacts of climate change in our mission to provide Silicon Valley with safe, clean water for a healthy life, environment, and economy. We’re preparing for wet and dry years, whether that means diversifying our water supply resources to protect us from droughts, or accounting for rising sea levels in our flood protection projects. Rising global temperatures and warmer oceans result in rising sea levels and altered weather patterns. This means more intense and longer heat waves and varying changes in rainfall (not enough or too much). All of these carry dangerous consequences for the Bay Area. The last decade has been riddled with record-setting temperatures. Every year has been warmer than the last, threatening our water supplies. In 2015, snowpack in the Sierra Nevada was dismal, leaving very little to melt and flow to the Delta, where we receive 40 percent of our water supply. With imported water supplies so vulnerable, the district is focused on diversification, including expanding our water conservation and water reuse programs. This helps protect our drinking water during droughts. We are also exploring additional storage opportunities such as an expanded Pacheco Reservoir to increase our emergency water supply.

  • Coastal Flooding - August 2016
    Climate Change Indicators in the United States: Coastal Flooding www.epa.gov/climate-indicators - August 2016 Coastal Flooding This indicator shows how the frequency of coastal flooding has changed over time. Background Changing sea levels are affecting human activities in coastal areas. Rising sea level inundates low-lying wetlands and dry land, erodes shorelines, contributes to coastal flooding, and increases the flow of salt water into estuaries and nearby groundwater aquifers. Higher sea level also makes coastal infrastructure more vulnerable to damage from storms. “Relative sea level change” refers to the height of the ocean relative to the land at a particular location. As relative sea level rises due to climate change (see the Sea Level indicator), one of the most noticeable consequences is an increase in coastal flooding. Flooding typically occurs during seasonal high tides (“king tides”) and storms that push water toward the shore. In recent years, however, coastal cities are increasingly flooding on days with less extreme tides or little wind, even on sunny days. Floods are happening more often as rising sea level reduces the gap between average sea level and the height of the land. Many coastal cities have defined minor or “nuisance” flooding thresholds. When water rises above this level, minor flooding typically occurs in some streets, many storm drains become ineffective, and a coastal flood advisory may be issued. Recurrent coastal flooding can cause impacts such as frequent road closures, reduced stormwater drainage capacity,

  • Coastal Storms Are a Reality for New York City, Arriving As Hurricanes, Tropical Cyclones ,And Nor’Easters When Certain Meteorological Conditions Converge
    CToaS AL STORMS CHAPTER 4.1 Coastal storms are a reality for New York City, arriving as hurricanes, tropical cyclones ,and nor’easters when certain meteorological conditions converge. Not only dangerous, these storms can be deadly, sustaining destructive winds, heavy rainfall, storm surge, coastal flooding, and erosion. Climate change and rising sea levels are likely to worsen their impacts. W HAT IS THE HAZARD? TROPICAL cycLONES Tropical cyclones are organized areas of precipitation and thunderstorms that form over warm tropical ocean waters and rotate counterclockwise around a low pressure center. Such storms are classified as follows: • A tropical depression is an organized system of clouds and thunderstorms with a defined low pressure center and maximum sustained winds of 38 miles per hour (mph) or less. • A tropical storm is an organized system of strong thunderstorms with a defined low pressure center and maximum sustained winds of 39 to 73 mph. • A hurricane is an intense tropical weather system of strong thunderstorms, a well-defined low pressure center (“eye”), and maximum sustained winds of 74 mph or more. In the North Atlantic Basin—where New York City is located—tropical cyclones often form in the Atlantic Ocean between Africa and the Lesser Antilles, in the Caribbean Sea, or in the Gulf of Mexico. Typically, they first track in a westerly or northwesterly direction. They are then pushed northward and eventually eastward by the force of the Earth’s rotation. They may track up the East Coast of the United States and reach New York City if water temperatures are warm enough and the prevailing winds steer them in this direction.
