a very few seagulls were working the updrafts on the cliffs.

海边峭壁上，寥寥几只海鸥正在向上奋飞。

an experiment to examine the vertical continuity of microphysical processes in relation to the supporting updrafts was conducted during the florida area cumulus experiment (face) in 1978.

本文利用face（佛罗里达积云试验）1978年夏季积云飞机实测资料，对微物理过程的垂直连续性及其和上升气流的关系进行了研究。

some viewers wondered if they were scraps of paper or plastic caught in updrafts from the spotlights「 heat.

一些目击者认为这也许是聚光灯中心处漂浮的纸屑和塑料碎片。

the warm, moist updrafts that feed them can pour 500 elephants into the storm each second.

温暖、潮湿的上升气流每秒钟向这些云朵内倾入与500头大象相同重量的水。

tornadoes form when the updrafts of air that supply storms with warm, humid air become a vortex, or high-speed whirlwind.

当上升气流与能形成风暴的湿热空气变成高速的旋风时，就形成了龙卷风。

the powerful updrafts and downdrafts can push a plane around, potentially damaging it or worse.

强烈的上下起伏可以导致飞机打转，对其造成潜在的危害甚至更严重的损害。

these massive seabirds use a wingspan topping 8 feet (2.5 meters) to glide gracefully, often for hundreds of miles, using thermal updrafts to gain altitude.

5米）优雅地滑翔，经常飞翔数百里，它们利用热上升气流升高。

others think bacteria might be sucked through updrafts caused by a special kind of lightning that travels upwards from cloud tops.

还有人认为，细菌也许是卷入了一种自云层顶端向上运行的特殊闪电造成的上升气流。

but without a raptor」s sharply honed sense for the gravity-defying updrafts , humans are beholden to chance.

但是如果没有猛禽们对克服重力的上升气流敏锐的判断力，人们常常错失良机。

the vertical flow over the urban generally consists of a close circulation characterized by strong daytime updrafts at the center city.

在沿城市的垂直剖面流场上组成了闭合的局地环流圈，白天垂直上升运动明显。

sea salts can enhance cloud drops number concentration under the case of large updrafts and decrease under the case of low updrafts.

而海盐粒子的存在，加剧了水汽的供应不足，从而可以在很大程度上进一步降低云滴数目。

some viewers wondered if they were scraps of paper or plastic caught in updrafts from the spotlights’ heat.

有些人以为这些物体可能是聚光灯发光时产生的热量捕捉到的漂浮在高空的纸片或塑料碎片。
