Why Do Balloon Flights Happen At Such A Early Hour?
为什么气球飞行会在这么早的时候进行？
In order for balloons to fly successfully, consistent winds are required, and the time right after sunrise is the optimum for locating these winds. Since balloons are airborne, the weather has a significant impact on whether or not they will fly. In order to fly toward a good landing spot using the wind currents, the pilot selects a launch point.
气球需要稳定的风才能有效运行，日出后的几个小时是寻找这些风的最佳时间。 由于气球随空气移动，因此天气对于决定是否飞行非常重要。 飞行员选择一个发射场，利用风流飞向一个合适的着陆点。
