Weather
Parameters Defined
Data for the weather forecasts is
gathered from several NOAA models and GFS models.
The following weather information is available for download. Surface Temperature The temperature 2 meters above the ground. Surface Pressure Surface pressure of the earth adjusted to mean sea level. Wind Speed Mean wind speed. Wind Direction(true) Mean wind direction, measured from true north. Wave Height Mean height of the 1/3 highest waves measured from crest to trough. Wave Direction(true) Mean wave direction, measured from true north. Wave Period Mean period between significant waves. Ice Pellets Precipitation in the form of ice pellets. Snowing Precipitation in the form of snow. Freezing Rain Precipitation in the form of freezing rain. Raining Precipitation in the form of rain. Visibility The range at which objects can be observed. UV Index Indicates the danger of exposure to UV radiation. Dew Point Temperature at which water in the atmosphere will condense given the current humidity level. Convective precipitation The precipitation rate over the user-selected Display Frequency, expressed in millimeters. Convective Cloud Cover The percentage of conventice cloud cover only (not all types of clouds). Atmospheric Instability Expressed on a scale of 6+ Very Stable Conditions to 6- Very Unstable, Severe Thunderstorms Likely Perceived Temperature The 'feels like' temperature given the relative humidity. Thunderstorm Probability A composite estimate of the probability of thunderstorms. |
