will “share” or “exchange” energy, creating massive areas of instability and turbulence between them that may be invisible to radar... and even to the eye. If there is any precipitaiton at all in an area of storms with moderate or greater precipitation returns, anywhere in the cluster, researchers tell us there is the chance of extreme turbulence hazard. Dr. Strahle warns that if thunderstorm complex has enough energy to create yellow or red radar returns, it has enough potential to create turbulence anywhere within or near the cloud.So, what exactly should you stay 20 miles away from? If there’s moderate, heavy or extreme precipiation in the cell at all (yellows, reds or worse), it’s not safe to be anywhere in the precipitation footprint of that cell. Remaining 20 miles clear of that thunderstorm means staying 20 miles or more away from the outside edges of even the lightest, green radar returns.Knowing what you know now, it’s a lot easier to make an informed go/no-go decision for flying when storms threaten. You know you’re not pushing your luck if you plan your flight to remain well away from anything that shows up on radar, to avoid the Updraft stage of individual storm cells and the potential of encountering significant turbulence as cells share and exchange energy between them. If you’re enroute and can’t stay well away from all the radar retu•rns surrounding heavy precipitation, deviate right away. If you can avoid driving on the greens, as it were, you can make a confident “go” decision. T&TTurbines, Inc.
