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。

The results show that the camber deformation may play an important role in lift and drag coefficients. The positive camber deformation of the hindwing during the downstroke generates the vertical force, whereas negative camber deformation of the wing during upstroke generates thrust force. The freely flying dragonfly's hindwings play an important role in providing a stable lift force, and the forewings are very important for controlling flight behavior, such as turning, climbing and so on.

From the sea ice motion data extracted from the MODIS and AVHRR images, it is found that the sea ice motion in the Bohai Sea is effected not only by prevailing winds but also by topographic steering, ocean currents and internal ice stresses. The extracted sea ice drift is similar to observed ice drift, and can clearly show the sea ice drift in the Marginal Ice Zone especially. It can compensate for the limitation of the local or single station observation.

The cause of the earth tide force is its elliptic orbit movement. There is the tide caused by the earth on the moon because the earth is the focus of the moon moving orbit, but there is not the tide caused by the moon on the earth because the moon is not the focus of the moving orbit of the seawater on the earth.

地球的潮汐力是由椭圆轨道运动产生的，由于月球的轨道运动是以地球为焦点，所以在月球上可以产生受地球影响的潮汐，而不可以产生相反的潮汐，因为海水或岩浆没有以月球为焦点的轨道运动。
