1154 results about "Severe weather" patented technology

Severe weather refers to any dangerous meteorological phenomena with the potential to cause damage, serious social disruption, or loss of human life. Types of severe weather phenomena vary, depending on the latitude, altitude, topography, and atmospheric conditions. High winds, hail, excessive precipitation, and wildfires are forms and effects of severe weather, as are thunderstorms, downbursts, tornadoes, waterspouts, tropical cyclones, and extratropical cyclones. Regional and seasonal severe weather phenomena include blizzards (snowstorms), ice storms, and duststorms.

System and method for providing personalized storm warnings

A system and method for generating storm warnings which are precisely tailored automatically for a particular individual or business user's geographic location of interest, which may be provided automatically to the individual user or business. The user establishes an individualized user profile, in which the user may define a particular location of interest and a contact address to which a personalized storm warning is to be delivered. The user may also establish a storm profile defining attribute characteristics of a storm for which the user desires a storm warning to be provided, and an amount of advanced warning to be provided by the personalized storm warning. A detailed and accurate storm track which includes information describing storm characteristics (severe weather conditions) as well as the current location and predicted track of movement of storm, is generated. The storm track may be generated automatically from weather radar data, such as NEXRAD data, either alone, or in combination with local live weather radar information, to provide a more accurate storm track. Generated storm tracks are compared to individual user profiles. Personalized storm warnings identifying in detail the storm conditions approaching a user location of interest and arrival time information for that location of interest are generated for user profiles defining locations of interest within a predicted storm track, if the storm track characteristics of the storm meet the attribute and advance warning characteristics specified in the storm profile established by the user. The personalized storm warnings may be delivered to users via e-mail, cell phone, pager, etc.

Storm alert automatic system power-down

Apparatus and processes to automatically power-down a computer system upon determination of the presence, imminence, or forecast of severe weather in the local area. A computer system receives data relating to a weather forecast for a particular local area from a weather service communication server and, based on a determination of the presence, imminence or forecast of severe weather in the local area, initiates an automatic power-down sequence. A delay may be provided to allow the user time to abort the initiation of the automatic power-down sequence. The data may be transmitted in any suitable manner, e.g., over a telephone line through the PSTN, using the Internet, using a paging system, etc. The weather service communication server is provided with the particular local area relating to the computer system. For instance, in the case of a dial-up telephone call to the weather service communication server, call related information such as the telephone exchange number and/or the area code in Caller ID information can be used by the weather service communication server to determine the local area relating to the particular computer system. Thus, a user is provided additional security against damage which may be caused to all or a portion of a computer system due to lightning strikes, downed telephone poles, etc. as a result of severe weather in a local area.
