These scenarios are unlike the static weather presets that ship with Microsoft Flight Simulator.\n\nWith real-time metar data as the foundation, the weather force weather engine provides a more realistic weather experience!\nThe metar data is updated 6x an hour and downloaded directly from NOAA and can provide accurate results within a 1/8th mile of a given point.\nWeather Force utilizes uniquely built algorithms to combine both metar and model data to cover sparse areas such as deserts and oceans.\nThe GFS (Global Forecast System) Model data is downloaded twice daily from NCEP and provides key atmospheric conditions to give a snapshot of temperature and winds aloft.\nRemarkably Unique\nWeather Force reads remarks provided with live metar reports to determine if storms are near the aerodrome. Thus, even if the automated metar may indicate clear conditions, if remarks indicate storms nearby, storms will be generated near the reporting station as in real life.\n\nPowerful Weather Search\nIf you are looking to fly at a particular location or in certain weather conditions, Weather Force includes a handy weather search feature that allows you to search by airport or by weather criteria.\n\nDynamic Changing Weather Scenarios (DCWS)\nTo add even more interest, Weather Force comes with dynamic changing weather scenarios (DCWS). These weather scenarios are dynamic, unlike the static default presets in Microsoft Flight Simulator. These Weather Force weather scenarios dynamically change over time and provide various elements of changing weather over the course of your flight. Examples provided below of included scenarios:\nFair weather\nApproaching cold front\nApproaching warm front\nHot and humid summer\nLake effect snows\nWinter storm\nCrisp winter\nBreezy\nSpring showers\nBecause DCWS are centralized on the REX servers, REX can periodically add new and exciting scenarios, which will be automatically added to your application without the need to update Weather Force.\n\nTracking The Weather\nIn Weather Force you have the ability to easily track your 10 favorite airports, therefore, clearly identifying what the detailed weather is like at each. If you require a more detailed report, simply click on the ICAO and receive in-depth data about the airport weather conditions.\n\nBehind the Scenes\nThe Goal\nWith Microsoft Flight Simulator, we have been provided a powerful weather system as a start. The goal is to provide an even more robust weather environment. The REX developers have worked diligently to render the weather as it should be, yet stay true to the validity of real-world metar data.\nSmoothing Mechanism\nIn addition, the REX developers have carefully added a smoothing mechanism to the engine to gradually smooth and transition the weather over time between updates. Of course, you have complete control over the weather update factors as well as transition speed.\nContinued and Consistent Development\nThe REX developers are dedicated to continuously develop and update Weather Force as new API’s become available from Asobo and Microsoft, thus they have developed an implementary system to deliver program updates quickly and easily to you.", "summary": "Weather Force is the new metar-based dynamic real-time weather engine for Microsoft Flight Simulator!
