Weather forecasting models each use a mathematical model of the atmosphere and oceans to forecast future weather conditions based on current weather conditions. Forecasts of future weather conditions may be output in the form of high resolution (still or moving) images that may be overlaid over a map or satellite image of a geographic area to graphically depict the predicted future weather conditions for the geographic area. Those high resolution images may be used as part of a television broadcast (such as a local news broadcast), published online (e.g., at AccuWeather.com), or distributed to the customers of weather forecasting companies.
Weather systems that are smaller than approximately 50 miles (or 60 kilometers) are generally referred to as “mesoscale” weather systems. Mesoscale weather systems are distinguished from larger “synoptic scale” weather systems and smaller “microscale” weather systems, which are short-lived atmospheric phenomena with widths of about 1 mile (or 1 km) or less.
No single weather forecasting model provides the most accurate forecasts of all mesoscale weather systems. Instead, each weather forecasting model has one or more biases. For example, when a mesoscale weather system is coming out of the southwestern United States (i.e., the Grand Canyon region) towards Kansas, Missouri, and Iowa, the Global Forecast System (GFS) model is known to output a long range forecast in which the predicted location of the mesoscale weather system is approximately 150 miles east of its most likely location. When preparing a forecast, an experienced meteorologist will often adjust for that bias by moving the forecasted location of a mesoscale weather system to the west.
In another example, Kansas and Oklahoma are often more humid in the spring than weather forecasting models predict. In other words, moisture often moves north from the Gulf of Mexico earlier than the weather forecasting models predict. As a result, thunderstorms can occur in Kansas and Oklahoma that are either not predicted by weather forecasting models or are predicted to occur farther east than their actual westernmost location. If an experienced meteorologist determines that a thunderstorm is likely to occur in Kansas and/or Oklahoma, the meteorologist adjusts for the known bias in the weather forecasting models by adding a mesoscale weather system (in this instance, a thunderstorm) where the meteorologist determines to be the most likely location,
A meteorologist will often prepare a forecast by mentally combining the forecasts of multiple weather forecasting models and adjusting for the biases of each individual weather forecasting model.
When the forecasts of weather forecasting models are mentally adjusted or combined, the high resolution images do not accurately reflect the meteorologist's forecast because the high resolution images still reflect the biases of the weather forecasting models. Instead, the meteorologist must graphically depict a forecast by drawing polygons either by hand or using computer-aided design tools, Accordingly, while a meteorologists hand-drawn forecast may be more accurate than what is provided by the weather forecasting models, the meteorologist's hand-drawn forecast lacks the high resolution detail provided by the weather forecasting models. A television meteorologist may even disagree with the high resolution forecast being depicted on screen, for example by describing a forecasted thunderstorm that is not graphically depicted based on the output of the weather forecasting model.
Additionally, if a meteorologist makes an adjustment to the forecast of an existing weather forecasting model, those existing weather forecasting models cannot make additional forecasts based on the meteorologist's adjustment. For example, an existing weather forecasting model may forecast weather conditions every six hours. After three hours, it may become apparent that the forecast was inaccurate. Existing weather forecasting models cannot be re-run with additional information correcting the inaccuracy. Instead, meteorologists must wait until the six-hour period has elapsed before the existing weather forecasting system forecasts weather conditions based on the accurate weather conditions.
Accordingly, there is a need for a mesoscale modeling system and method that enables meteorologists to adjust forecasts to account for known biases of weather forecasting models and outputs high-resolution images consistent with the adjusted forecasts, There is also a need for a mesoscale modeling system and method that uses a weather forecasting model to forecast future weather events based on one or more adjustments to one or multiple models provided by the meteorologists.
In order to overcome these and other disadvantages in the related art, there is provided a mesoscale modeling system and method that enables meteorologists to adjust forecasts to account for known biases of weather forecasting models and outputs high-resolution images consistent with the adjusted forecasts. The mesoscale modeling system and method may also use a weather forecasting model to forecast future weather events based on one or more adjustments provided by the meteorologists.
