As a result, these events are officially known as " wind anomalies from thermal convection" .

因此，这些事件被正式称为“热对流引起的风异常”。

These powerful flyers use thermal convection  currents to soar through the air, reaching speeds of 50 to 70 kilometers an hour when gliding  and 120 to 160 kilometers an hour while diving.

这些强大的传单利用热对流在空中翱翔，滑翔时达到每小时 50 到 70 公里的速度，潜水时达到每小时 120 到 160 公里。
