教学目标:(1)能够说出气流垂直运动与天气现象的关系。(2)能够辨认冷锋与暖锋符号。(3)能够说出冷锋过境和暖锋过境时的天气特点。过程与方法:(1)通过云雾产生的条件推测气流垂直运动与天气的关系。(2)结合教材中锋面形成示意图,探究冷锋符号和暖锋符号的含义。(3)通过绘制冷、暖锋锋面上的气流运动状况,推断冷锋和暖锋过境时的天气特点。(4)通过古典文学的朗读和模拟预报天气,体验锋面过境的天气变化。
Teaching Objectives: (1) Be able to say the relationship between the vertical movement of the airflow and the weather phenomenon. (2) Can identify cold front and warm front symbol. (3) Be able to say the weather characteristics of cold fronts transit and warm front transit. Process and method: (1) infer the relationship between the vertical movement of the airflow and the weather through the conditions generated by the cloud. (2) With the schematic diagram of the center of the textbook, explore the meaning of cold front sign and warm front sign. (3) By plotting the air movement on the front of warm and cold front, we can deduce the weather characteristics of cold front and warm front transit. (4) Through the reading and simulation of classical literature, forecast the weather and experience the weather changes in frontal transit.
