    The FOX Forecast Center is monitoring flights across the eastern U.S. on Wednesday. ... This could also lead to slightly increased turbulence, especially in the form of Clear Air Turbulence (CAT).

  3. Ellrod index - Wikipedia

    en.wikipedia.org/wiki/Ellrod_index

    In meteorology the Ellrod index is a technique for forecasting clear-air turbulence (CAT). It is calculated based on the product of horizontal deformation and vertical wind shear derived from numerical model forecast winds aloft. The deformation predictors are calculated using following information. Shearing deformation:

  4. What to know about air turbulence before your next flight - AOL

    AWC forecasts, in text and chart, conditions over all of the continental United States from the surface to over 20 km altitude (Aviation Area forecast). [1] These include freezing level, icing, wind and turbulence levels, cloudy areas and thunderstorms at various altitudes.

  6. Clear-air turbulence - Wikipedia

    en.wikipedia.org/wiki/Clear-air_turbulence

    A horizontal temperature gradient may occur, and hence air density variations, where air velocity changes. An example: the speed of the jet stream is not constant along its length; additionally air temperature and hence density will vary between the air within the jet stream and the air outside. Cirrus clouds often associated with clear-air ...

    Data from turbulence prediction website Turbli, which has analysed around 150,000 routes, shows the most turbulent journeys of 2023. Routes are ranked according to “eddy dissipation rate ...

  8. SIGWX - Wikipedia

    en.wikipedia.org/wiki/SIGWX

    The SIGWX charts only show the forecast for the specific hour, however it is common place for parameters such as the JetStream, CAT & CB to be interpreted +/- 3 hours of the chart validity time. . Prognoses are typically prepared for two ranges of heights: SWH - High Level SIGWX (Flight level 250-630) SWM - Medium Level SIGWX (Flight level 100-450)
