Not until October 1945 did the Americans expect to have a jet airplane (and in the event, two years after the end of the war, the ME 262 being flown at Wright-Patterson AFB, Dayton, Ohio, was still judged superior to the new USAF-80 jet fighter).

到1945年10月前，美国才有望拥有喷气飞机（例如，战争结束两年后，飞行在俄亥俄州戴顿县莱特—帕特森空军基地上空之ME262，比较起新式美国空军*—80式喷气战斗机来，还被判定更为出色）。

The STE dominated by the intrusion of stratospheric air has been testified as a cause of ozone enhancement in upper troposphere over East Asia at the end of March 2001. This STE relates to the surface high moving southward, the upper cold eddy deepening and drifting eastward, the convergence of Subtropical Jet and Polar Front Jet associated with the cold front, the increasing temperature gradient near the jets, and the enhancing baroclinic instability.

天气诊断和动力分析表明，2001年3月底东亚地区几个臭氧探空测站探测到的对流层上层臭氧增加是以平流层空气下传为主的STE过程导致的，此过程与地面冷高压南下、高空冷涡加深东移的天气过程、以及冷锋推进引起的副热带急流和极锋急流的移动和汇合、急流附近的温度梯度加大、斜压不稳定增强等动力因素密切相关。
