3 Reasons Microbursts Are More Hazardous In The Mountains

Microbursts are dangerous anywhere, but in the mountains, they pose an even greater threat.

1) Dry Climate

The southwestern region of the United States has the driest climate in the country. As a result, even light rain can create strong downdrafts as rain evaporates on its way to the ground. This creates virga and dry microbursts, which are microbursts without precipitation that can be difficult to detect visually, especially from lower altitudes.

2) Valley Wind Break-In

Microbursts are most commonly found in the dissipating stage of a thunderstorm. On flat ground in most of the United States, a microburst will disperse in all directions. However, in the mountains, the slopes restrict where the downdrafts flow.

The valleys act as a funnel that redirects the downdraft parallel to the valley walls. Since the energy of the downdraft isn't able to be dispersed in all directions, the flow of air racing down the valley is accelerated, posing a wind shear risk to your aircraft.


3) Degraded Climb Performance

If you're climbing over mountains, then odds are you're at a fairly high altitude. Depending on the type of aircraft you're flying, you may be nearing the limits of your aircraft's climb performance. Combine this with downdrafts associated with microbursts (which can be over 6,000 ft/min) or virga, and your aircraft's performance limitations can easily be exceeded.

It's easy to think that mountain weather only happens in places like the Rockies. But the hills of Eastern Ohio can produce the same types of weather year-round. If you've ever flown near the Appalachians, you probably experienced mountain weather, even if you didn't realize it was happening.

Whether you're flying on the East Coast, the Coastal Ranges of California, or any of the rough terrain in between, Boldmethod's Mountain Weather course makes you confident and comfortable flying around the mountains.

You'll learn how to evaluate mountain weather during your planning and while you're in flight. You'll also learn how terrain generates updrafts, downdrafts, turbulence, and storms, and changes the direction of the wind throughout the day.

Plus, for less than the cost of a cross-country flight, you get lifetime access to tools that increase your confidence and make your flights more fun.
