Reflectivity: Radar term referring to the ability of a radar target to return energy; used to estimate precipitation intensity and rainfall rates.

Refraction: The bending of light as it passes through areas of different density, such as from air through ice crystals.

Relative humidity: The amount of water vapor in the air, compared to the amount the air could hold if it was totally saturated. (Expressed as a percentage).


S.A.M.E.: Specific-Area Message Encoding. This feature of weather radios only alerts you to advisories in your area. You must enter your desired codes into the radio. Seneca county is : 039147.

Saffir-simpson hurricane damage potential scale: A scale that measures hurricane intensity, developed by Herbert Saffir and Robert Simpson.

SATA: SATA Serial ATA. Offers much more speed than traditional ATA drives.

Scattered: A cloud layer that covers between 3/8ths and 1/2 of the sky.

Severe thunderstorm: A strong thunderstorm with wind gusts in excess of 58 mph (50 knots) and/or hail with a diameter of 3/4" or more. A thunderstorm with winds greater than 39 mph and/or hail greater than ? inch is defined as approaching severe.

Severe thunderstorm warning: Issued when thunderstorms are expected to have wind gusts to 58 mph or above or hail 3/4 inch or more in diameter.

Severe thunderstorm watch: Issued when conditions are favorable for the development of severe thunderstorms in and close to a defined area.

Slight chance: In probability of precipitation statements, usually equivalent to a 20 percent chance.

Small craft advisory: A marine advisory for winds 25 to 33 knots (29 to 38 mph) or seas of 5 feet or more, that may cause hazardous conditions for operators of small vessels.

Smog: Pollution formed by the interaction of pollutants and sunlight (photochemical smog), usually restricting visibility, and occasionally hazardous to health.

Smoke: A suspension in the air of small particles produced by combustion. A transition to haze may occur when smoke particles have traveled great distances (25 to 100 statute miles or more) and when the larger particles have settled out and the remaining particles have become widely scattered through the atmosphere.

Snow: Frozen precipitation composed of ice particles in complex hexagonal patterns. Snow forms in cold clouds by the direct transfer of water vapor to ice.

Snow advisory: Older terminology replaced by winter weather advisory. An advisory issued when 4, 5, or 6 inches of snow or sleet is expected in 24 hours. It is expected to create hazardous or restricted travel conditions, but not as severe as expected with a winter storm.

Snow depth: The vertical height of frozen precipitation on the ground. For this purpose, frozen precipitation includes ice pellets, glaze, hail, any combination of these, and sheet ice formed directly or indirectly from precipitation.

Snow flurries: Light snow showers, usually of an intermittent nature and short duration with no measurable accumulation.

Snow grains: Precipitation of very small, white, opaque grains of ice.

Snow pellets: Precipitation of white, opaque grains of ice. The grains are round or sometimes conical. Diameters range from about 0.08 to 0.2 inch (2 to 5 mm).

Snow shower: Snow falling at varying intensities for brief periods of time. Some accumulation is possible.

Snow squalls: Intense, but of limited duration, periods of moderate to heavy snowfall, accompanied by strong, gusty surface winds and possible lightning.

Snowburst: Very intense shower of snow, often of short duration, that greatly restricts visibility and produces periods of rapid snow accumulation.

Snowfall: The depth of new snow that has accumulated since the previous day or since the previous observation.

Statement: Provides the public with information concerning the status of existing warnings.

Storm: In marine usage, winds 48 knots (55 mph) or greater.

Storm surge: A rise of the sea level alone the shore that builds up as a storm (usually a hurricane) moves over water. It is a result of the winds of the storm and low atmospheric pressures.

Storm track: the path that a low pressure area follows.

Storm warning: A marine wind warning for sustained winds greater of 48 knots (55 mph) or more from a non-tropical system.

Storm-relative: Measured relative to a moving thunderstorm, usually referring to winds, wind shear, or helicity.

Storm-scale: Referring to weather systems with sizes on the order of individual thunderstorms. See synoptic scale, mesoscale.

Straight line winds: Thunderstorm winds most often found with the gust front. They originate from downdrafts and can cause damage which occurs in a "straight line", as opposed to tornadic wind damage which has circular characteristics.

Stratocumulus: Low-level clouds, existing in a relatively flat layer but having individual elements. Elements often are arranged in rows, bands, or waves.

Subtropical jet: The branch of the jet stream that is found in the lower latitudes.

Subtropical storm: A low pressure system that develops in subtropical waters (north of 20 north degrees latitude) and initially has non-tropical features (see table below for a list of tropical features) but does have some element of a tropical cyclone's cloud structure (located close to the center rather than away from the center of circulation).

Supercell thunderstorm: A severe thunderstorm whose updrafts and downdrafts are in near balance allowing the storm to maintain itself for several hours. Supercells often produce large hail and tornadoes.


Tornado: A violent rotating column of air, in contact with the ground, pendant from a cumulonimbus cloud. A tornado does not require the visible presence of a funnel cloud. It has a typical width of tens to hundreds of meters and a lifespan of minutes to hours.

Tornado alley: The area of the United States in which tornadoes are most frequent. It encompasses the great lowland areas of the Mississippi, the Ohio, and lower Missouri River Valleys. Although no state is entirely free of tornadoes, they are most frequent in the Plains area between the Rocky Mountains and Appalachians

Tornado warning: Issued when there is likelihood of a tornado within the given area based on radar or actual sighting. It is usually accompanied by conditions indicated for Severe Thunderstorm Warning.

Towering cumulus: A large cumulus cloud with great vertical development, usually with a cauliflower-like appearance, but lacking the characteristic anvil shaped top of a Cb. (Often shortened to "towering cu," and abbreviated TCU.)

Trade winds: Persistent tropical winds that blow from the subtropical high pressure centers towards the equatorial low. They blow northeasterly in the Northern Hemisphere.

Tropical depression: Tropical mass of thunderstorms with a cyclonic wind circulation and winds near the surface between 23 mph and 39 mph.

Tropical disturbance: An organized mass of thunderstorms in the tropics than lasts for more than 24 hours, has a slight cyclonic circulation, and winds less than 23 mph.

Tropical storm: An organized low pressure system in the tropics with wind speeds between 38 and 74 mph.

Tropical storm warning: A warning issued when sustained winds of 39 to 73 mph (34 to 63 knots) are expected within 24 hours.

Tropical wave: A kink or bend in the normally straight flow of surface air in the tropics which forms a low pressure trough, or pressure boundary, and showers and thunderstorms. Can develop into a tropical cyclone.

Twister: A colloquial term for a tornado.


Updraft: A small-scale current of rising air. This is often associated with cumulus and cumulonimbus clouds.

Upper level system: A general term for any large-scale or mesoscale disturbance capable of producing upward motion (lift) in the middle or upper parts of the atmosphere.

UPS: Uninterpretable Power Supply (UPS) is an electrical power accessory that provides emergency power connected devices when the input power source, typically mains power, fails. They also can serve as line conditioners if the voltage is not clean.
