So , the paper suggests that the fixed - bed updraft gasifier use the wet air as gasifying preparation 本文建议,上吸式气化炉采用湿空气作气化剂。

By contrast , vaughan williams ' s lark is an ethereal solo violin effortlessly floating on updrafts of sound 佛汉威廉士的云雀是轻柔的小提琴独奏，乐韵潇酒地于空中飞舞。

Finally , the mechanism for the effect of the updraft restraint of the hailstorm on micro - physical processes is analyzed 最后，文中还分析了人工抑制上升气流影响云中冰雹形成的微物理机制。

Peak updraft strength is slightly enhanced with hodograph curvature , 29 . 0 m / s in b versus 26 . 1 in c 山顶上升气流强度随速矢端迹曲率加大而稍有加强，在（图上） b点是每秒29米， c点是每秒26 . 1米。

As the hot air rises , a powerful updraft is also created by the tower that allows air to be continually sucked through 32 turbines , which spin to generate power 24 hours a day 当热空气上升时，一股有力的上升气流被可以让32个涡轮持续吸引的塔所生成，那些涡轮可以产生24小时的动力来纺纱。

But in flood years , the convergences in mid - and low - level of troposphere are strong . divergence departure in 200hpa is positive , so the pumping cause the updraft stronger . as we all know , the updraft is better to the rain 涝年对流层中下层辐合偏强， zoohpa上，高原东北侧地区为正散度距平区，辐散较常年偏强，高空辐散抽吸作用使得该区盛行上升气流，有利于降水的形成。

The diagnostic analysis for the sandstorm process on the base of height , temperature , pressure and wind etc output from the model shows that the upper cold trough , low - level wind shear , surface cold anticyclonic ridge , mesoscale cyclone and cold front are the main synoptic systems , surface cold anticyclonic ridge and cold front provide condition of wind force to occurrence of the sandstorm weather , the strong mesoscale cyclone before front makes pressure gradient before and after cold front obviously strengthen , moreover , and it increases obviously the temperature of the controlled area , as a result , the updraft movement caused by convergence before front strengthens 500hpa强锋区、 700hpa切变和锋前中尺度系统的强弱及位置变化是沙尘暴天气发生发展到减弱的直接原因。地面冷高压、地面气旋及冷锋是造成本次沙尘暴天气的主要地面天气系统。地面冷高压及冷锋为沙尘暴天气的发生提供了风力条件，而中尺度气旋使冷锋前后气压梯度明显增强外，又使所控制的区域增温明显，使锋前辐合上升运动加强，为沙尘暴天气的发生提供了热、动力条件。
