根据最近在肯尼亚北方的气球观测资料，指出在分隔埃塞俄比亚高原和东非高原的图尔卡纳海峡存在一股强烈的东南向低空急流。喷流全年都存在，速度有时超过30 m s−1（60 kt），有时超过50 m s−1（100 kt）。在2月和3月期间，基于早晨观测的月平均风速超过25 m s−1（50 kt）。上午的风比下午的风更强，这可能是由于下午急流最大值的垂直混合和稀释更强。速端图从最低层到地面以上0.75公里（2500英尺），有时甚至在高处逆时针方向旋转。在离地面0.45公里（1500英尺）的高度，速端线显示出南半球埃克曼层的一些特征。这种喷气式飞机不同于现在众所周知的东非低空喷气式飞机（发现...
Abstract On the basis of recent pilot balloon observations which have become available in northern Kenya, it is shown that there exists a strong southeasterly low-level jet in the Turkana Channel which separates the Ethiopian Highlands the East African Highlands. The jet exists throughout the year, with speeds exceeding 30 m s−1 (60 kt) on a number of occasions and sometimes exceeding 50 m s−1 (100 kt). During February and March, the mean monthly winds based on the morning observations exceed 25 m s−1 (50 kt). The morning winds are stronger than afternoon winds, presumably due to stronger vertical mixing and dilution of the jet maximum in the afternoon. The hodograph turns in a counterclockwise direction from the lowest levels up to 0.75 km (2500 ft) above ground level and sometimes even aloft. Up to 0.45 km (1500 ft) above ground level, the hodograph manifests some of the characteristics of the Southern Hemisphere Ekman layer. This jet is different from the now well-known East African low-level jet (Find...
