低空急流是在大气低层出现的狭窄强风带。 |
| 3. | Water vapor in the lower atmosphere can vary in amount from a mere trace in arid regions to about 4 % by volume in moist areas
大气低层的水汽量在干燥地区（量）甚微，而在潮湿地区按体积占4 %左右。 |
| 4. | From the night of 22 march friday to 23 march saturday , a cold front will reach southern china and winds over the lower atmosphere will change to northerlies then
星期五晚至23日星期六，一道冷锋会抵达华南地区，届时大气低层会转吹北风。 |
| 5. | Will include a global warming of the earth s surface and the lower atmosphere as warming up is the simplest way for the climate to get rid of the extra energy
这转变可包括全球性的地球表面及大气低层变暖，因为这样可以将过剩的辐射排放出外。 |

| 7. | Of the earth s surface and the lower atmosphere as warming up is the simplest way for the climate to get rid of the extra energy . however , a small rise in temperature will induce many other changes , for example , cloud cover and wind patterns
这转变可包括‘全球性’的地球表面及大气低层变暖，因为这样可以将过剩的辐射排放出外。虽然如此，地球表面温度的少许上升可能会引发其他的变动，例如：大气层云量及环流的转变。 |
| 8. | 3 ) this paper identifies the sensitivity location and variables of 6h forecast errors by the method of adjiont sensitivity analysis also , and they locate west and south west of the real rainfall field . the forecast skill may be improved if low - level observation data is of high quality
3 )用伴随敏感性分析方法确定了影响南京暴雨前6小时预报的敏感性区域，它们位于对流层低层雨区的西侧及西南方向，改善大气低层要素的观测和分析质量能够进一步提高预报水平。 |
| 9. | The basic requirements include good cyclonic inflow i . e . for the northern hemisphere , inward spiralling in an anti - clockwise sense at the lower levels for the initial spin - up process , and good outflow channels at the upper levels for effective ventilation . the convergence of air at the lower levels and divergence aloft imply a vertical circulation which is schematically shown in the following cross - sectional diagram
热带气旋的诞生及发展的基本条件是：在大气低层必须有充份的气旋式气流辐合（在北半球，沿反时针方向螺旋形地流入） ，在大气高层要提供足够的气流外溢通道，这样才可以建立有效的通风机制。 |
| 10. | Otherwise , further development and intensification will be inhibited . the basic requirements include good cyclonic inflow i . e . for the northern hemisphere , inward spiralling in an anti - clockwise sense at the lower levels for the initial spin - up process , and good outflow channels at the upper levels for effective ventilation
