查询词典 updrafts

When the conditional instability lies in the lower level and conditional symmetric instability in the upper level , the circulation will have vertical updrafts in the lower level and slantwise updrafts in the upper level .

当低层和高层出现条件不稳定，中间呈条件对称不稳定或弱稳定度层结时，从低层到高层出现较深厚的垂直上升气流，湿重力不稳定能量的释放导致了云带的形成。

The conditional symmetry instability is the intermediate process between the stable and instable states of the atmosphere. The evolution of the atmosphere from the stable to unstable state or from unstable to stable state comes through two stages. The convective-symmetric instability circulation is related with the state and type of the instability. When the conditional instability lies in the lower level and conditional symmetric instability in the upper level, the circulation will have vertical updrafts in the lower level and slantwise updrafts in the upper level. The release of conditional symmetric instability gives rise to a mesoscale rain belt.

结果表明：条件对称不稳定是大气稳定状态和条件不稳定状态之间的中间纽带，大气由稳定向不稳定或者由不稳定向稳定的演变均通过条件对称不稳定来实现；对流对称不稳定环流的形成与不稳定层的配置有关，当低层为条件不稳定而高层叠加深厚的条件对称不稳定时，对流对称不稳定环流低层出现垂直上升气流，高层出现范围较广的倾斜上升气流，对称不稳定能量释放产生中尺度云带。

He included in his column of air the way convective updrafts carry heat up from the surface, a basic process that nearly every earlier calculation had failed to take into account.

在他的模型中，他加入了上升气流携带的热力的影响。这个基本的过程是几乎早期的每个计算方法都忽略了的。

When the conditional symmetric instability lies in the middle level and conditional instability in the lower and upper levels, the circulation will have updrafts through the total column of the atmosphere. The release of conditional instability gives rise to a mesoscale rain belt.

当低层和高层出现条件不稳定，中间呈条件对称不稳定或弱稳定度层结时，从低层到高层出现较深厚的垂直上升气流，湿重力不稳定能量的释放导致了云带的形成。

In Gregory scheme, not only the importance of the moist static energy is taken into account, but also the common difficulty of the moist convective adjustment scheme, the determination of the temperature profile, is obviated. At the same time, it can give the vertical profile of the apparent heat source Q〓 and apparent moisture sink Q〓. Gregory scheme has the clear physical image that includes the cumulus updrafts, cumulus downdrafts,cumulus induced subsidence in the environmental air, entrainment,detrainment and evaporation. In addition, the interaction between the cumulus and the environment is described by one-dimensional bulk model. It is simpler than the Arakawa-Schubert scheme and has no difficult to decide the spectrum of clouds accurately.It is propitious to operational use because of its simple calculation. Finally, Gregory scheme is not only suitable for moist convection of all types, but also for dry convection.

在该方案中，既强调了湿静力能能量的重要性，又回避了给定临界温度廓线的困难，并且还能给出真实的视热源Q1，视水汽汇Q2的垂直廓线；同时Gregory方案又具有很清晰的物理图象—积云中的上升运动，下沉运动，环境中的补偿下沉运动，以及卷入，卷出和蒸发等；此外，Gregory方案用总体云群模式来描述云与环境的相互作用，比型积云参数化方案简单，它避开了型方案中云谱需要精确设置的麻烦问题，计算容易，简便；最后，Gregory方案在湿对流中适用于浅，深，中不同的对流深度，并且也适用于干对流过程。

It is indicated that the updrafts of the Arabian Sea meridional cell tube and the south zonal cell tube arrive in the SCS at the same time in May, which brings strong convective precipitation. Meanwhile, the westerly of the meridional cell tube and the southerly of the south zonal cell tube combine together to form the southwesterly at the low levels, resulting in the onset of the SCS monsoon.

研究发现阿拉伯海经向环流管的上升气流和南半球纬向环流管的上升气流在5月份同时到达南海，经向环流管低层的偏西风和纬向环流管低层的偏南风共同组成西南风，于是5月份西南季风在南海地区首先爆发。

Much of the released energy drives updrafts that increase the height of the storm clouds, speeding up condensation.

大部分释放能量驱动updrafts增加的高度风暴云层，加快凝结。

Pachomius manual labour was organized as an essential part of the monastic life; and since it is a principle of the monks as distinguished from the mendicants, that the body shall be self-supporting, external work of one sort or another has been an inevitable part of the life ever since.
