Forecast tropopause heights and lows
The elevation at which tropopause heights and lows occur can be an important factor for aircraft engine performance along a planned flight path when potentially significant weather, such as a thunderstorm, is forecast.
You can use the Tropopause heights and lows weather layer to show the forecast heights and lows as updated at 06:00, 12:00, 18:00 and 00:00 to include this information in your flight planning and tracking activities.
Click the Layers button.
Click the BASIC tab.
Navigate to the Tropopause Heights and Lows option.
Scroll, as needed, to the bottom of the tab.
Click the Tropopause Heights and Lows slider.
You may need to scroll again to display the option's sub-pane.
You can display the forecast heights and the forecast lows independently, or together.
For this example, enable both sliders.
Click the Heights Forecast Hours slider.
By default, the forecast heights and lows display for 6 hours in the future. The forecast is updated at 06:00, 12:00, 18:00 and 24:00 (00:00). You can use the control to display the forecast farther out from the current time to see trends.
Click the Lows Forecast Hours slider.
The white double lines that look like elevation lines represent the forecast tropopause heights.
As with other weather features, if you hover your mouse near the Forecast Height line, N-Tracking displays more detailed information, indicating the tropopause height is located at 40,000 ft.
The shield-shaped icons indicate tropopause lows and the flight levels at which they occur; in this example, 42,000 ft.
Congratulations! You can display tropopause forecast heights and lows to assist to your weather monitoring and flight planning and tracking activities.
