A Winter Forecasting Handbook Winter Storm Information That Is Useful to the Public
A Winter Forecasting Handbook Winter storm information that is useful to the public: 1) The time of onset of dangerous winter weather conditions 2) The time that dangerous winter weather conditions will abate 3) The type of winter weather to be expected: a) Snow b) Sleet c) Freezing rain d) Transitions between these three 7) The intensity of the precipitation 8) The total amount of precipitation that will accumulate 9) The temperatures during the storm (particularly if they are dangerously low) 7) The winds and wind chill temperature (particularly if winds cause blizzard conditions where visibility is reduced). 8) The uncertainty in the forecast. Some problems facing meteorologists: Winter precipitation occurs on the mesoscale The type and intensity of winter precipitation varies over short distances. Forecast products are not well tailored to winter Subtle features, such as variations in the wet bulb temperature, orography, urban heat islands, warm layers aloft, dry layers, small variations in cyclone track, surface temperature, and others all can influence the severity and character of a winter storm event. FORECASTING WINTER WEATHER Important factors: 1. Forcing a) Frontal forcing (at surface and aloft) b) Jetstream forcing c) Location where forcing will occur 2. Quantitative precipitation forecasts from models 3. Thermal structure where forcing and precipitation are expected 4. Moisture distribution in region where forcing and precipitation are expected. 5. Consideration of microphysical processes Forecasting winter precipitation in 0-48 hour time range: You must have a good understanding of the current state of the Atmosphere BEFORE you try to forecast a future state! 1. Examine current data to identify positions of cyclones and anticyclones and the location and types of fronts. -

ESSENTIALS of METEOROLOGY (7Th Ed.) GLOSSARY
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.) Mesosphere The atmospheric layer between the stratosphere and the thermosphere. -

A meteorological and blowing snow data set from the high-elevation experimental site of Col du Lac Blanc (2720 m a.s.l., Grandes Rousses mountain range, French Alps) is presented and detailed in this pa- per. Emphasis is placed on data relevant to the observations and modelling of wind-induced snow transport in alpine terrain. This process strongly influences the spatial distribution of snow cover in mountainous terrain with consequences for snowpack, hydrological and avalanche hazard forecasting. In situ data consist of wind (speed and direction), snow depth and air temperature measurements (recorded at four automatic weather stations), a database of blowing snow occurrence and measurements of blowing snow fluxes obtained from a vertical pro- file of snow particle counters (2010–2016). -
Hail Size and Melting Considerations in Thunderstorms
Hail Size and Melting Considerations in Thunderstorms NWS Louisville, KY Hail Size and Melting Considerations Two primary factors associated with surface hail size: • Hail generation and initial size in storm • How much melting occurs as hail falls to ground Factors Contributing to Hail Generation and Size in Storm • Storm type: supercells produce larger hail than quasi-linear convective systems (QLCSs) and pulse storms; incipient cells (intense updraft) produce larger hail than after cells congeal into a mesoscale convective system (MCS) • Storm tilt: updraft/downdraft separation promotes hail growth • Updraft strength: increases hail generation and residence time in storm • Dry air aloft (~800-500): leads to evaporative cooling which promotes hail growth and size • Steep mid-level lapse rates: suggests presence of mid-level cool/dry air; promotes strong updraft • Echo tops: taller storms can tap colder air aloft (high refl above -20° C levels) and increase hail residence time in cloud • Cell/boundary mergers: promotes stronger updraft and better chance for hail formation • Values of WBZ height: hail is most favorable with height of 7-12 kft; less favorable if < 6 kft (air mass too cool, although small hail/graupel likely from low-top storms) and if >> 12 kft (melting) The size of hail at surface can’t be determined from looking at reflectivity values in a storm alone Factors Contributing to Hail Size at Surface • Large stones: better chance to reach ground than small stones which melt faster on their descent • Stones melt faster in wet environment than in dry (RH has strong effect); dry air in ~800-500 mb layer is very important to produce evaporative cooling and limit hail melting during descent (why stones are smaller or non-existent during MCSs due to saturated environment – and weaker updraft) • Hail falling within rain melts at a much greater rate than hail falling separate from rain (especially for small hail) • Vertical wind shear is critical in surface hail size to separate the updraft and downdraft and limit duration hail falls in heavy rain. -
Chemical Properties of Snow Cover As an Impact Indicator for Local Air Pollution Sources

The analysed samples of snow were collected at 18 measurement sites located along the axis of cardinal directions of the world and with a central point in the urban area of Ostrowiec Świętokrzyski in January 2017. Chemical com- position was determined using the Dionex ICS 3000 Ion Chromatograph at the Environmental Research Laboratory of the Chair of Environmental Protection and Modelling at the Jan Kochanowski University in Kielce. The obtained results indicated a substantial contribution of pollutants pro- duced by a local steelworks in the chemical composition of melted snow. Keywords: precipitation chemistry, anthropopressure, snow cover INTRODUCTION The use of snow cover as an indicator for the magnitude of deposition of atmospheric air pollutants has already had several decades of tradition in Poland and Europe (Engelhard et al. 2007, Kozłowski et al. 2012, Siudek et al. 2015, Stachnik et al. 2010,).

Flood ACC Article
Breadth of the Flood Exclusion: A Flood is a Flood, Including Storm Surge TRED R. EYERLY A case involving an Alaska Native Corporation and property damage caused by a hurricane is bound to be of interest. Arctic Slope Regional Corp. v. Affiliated FM Ins. Co. did not disappoint.1 The Arctic Slope Regional Corporation, based in Barrow, Alaska, and one of the thirteen Corporations formed under the Alaska Native Claims Settlement Act of 1971, owned an office and construction yard in Iberia Parish, Louisiana. The property was inundated with three feet of water after Hurricane Rita’s storm surge hit in September 2005. Arctic Slope filed a claim for property damage with Affiliated. The claim was denied and suit was filed. Before the district court, the parties disputed which policy provisions applied to the storm surge related claims. The distinction was critical because the policy covered damage caused by “Wind and/or hail,” but excluded damage caused by flood. The policy defined “Wind and/or hail” as “direct and/or indirect action of wind and all loss or damage resulting there from whether caused by wind, by hail or by any other peril . when water . is carried, blown, driven, or otherwise transported by wind onto or into said location.” “Flood,” on the other hand, was defined as “surface water; tidal or seismic sea wave; rising (including overflowing or breaking of boundaries) of any body of water . all whether driven by wind or not. .”2 1 Arctic Slope argued that, because storm surge is caused by strong onshore winds, coverage was provided under the “Wind and/or hail” definition.
