| 1. | This form of convectional activity is responsible for thunderstorms .
这种形式的对流活动就是大雷雨形成的原因。 |
| 2. | Energy can be released and intense convective activity and maybe thunderstorms are likely to develop .
能量能够释放，就可能发展强对流活动甚至雷暴。 |
| 3. | In an unstable and moist atmosphere , water droplets and ice pellets in the cloud will become electrically charged in convective motion
在不稳定及潮湿的大气中，云层内的水滴及冰粒在对流活动中产生电荷。 |
| 4. | In an unstable and moist atmosphere , water droplets and ice pellets in the cloud will become electrically charged in convective motion
在不稳定及潮湿的大气中，云层内的水滴及冰粒在对流活动中产生电荷。 |
| 5. | This pattern of ssta distribution is related to summer rainfall anomaly of north china by means of the tropical convection activity and general circulation in the middle and high latitude
这种海温异常分布型可通过夏季热带对流活动和中高纬大气环流与华北夏季降水异常产生联系。 |
| 6. | There is teleconnection relations between shandong summer rainfall and the convective activities happening in tropical areas in spring and summer accomplished by rossby waves
通过分析强弱季风年春、夏季热带地区olr场的分布特征，发现热带地区的对流活动与山东夏季降水之间存在着遥相关关系。 |
| 7. | Turbulence usually happen in the vicinity of thundery showers where vigorous convective activities occur . it will also appear in areas where air masses with different speed , direction or temperature meet each other
湍流大多是发生在强烈对流活动(如雷雨区)附近出现，它亦会在不同速度、方向或温度的气流相遇之处出现。 |
| 8. | Weather information indicates that the region was affected by a broad rain band with vigorous convective activities at that time . it is estimated that the height of the clouds associated with the thunderstorms reached 45000 feet ( 15000 meters )
天气资料显示，当时该区正受到一度广?雨带影响，而且对流活动强烈，云带顶部高度估计达到45000尺（ 15000米） 。 |
| 9. | With the arrival of the front , the relatively warm air being less dense became lifted by the advancing cold air . the upward motion resulted in convection , eventually producing thunderstorms over the western coast of guangdong , the new territories and lantau ( figs
当冷锋抵达时，推进中的冷空气使密度较低的暖空气向上抬升，继而触发对流活动，其后为广东西部沿岸、新界及大屿山带来雷暴(图2至4 ) 。 |
