Development of the Earth-model experiment apparatus on meteorology required for natural science education

本研究利用地球模型实验装置，得到了曲波数的实验结果。(1)在中纬度地区，随着气温的升高，其数量有减少的趋势。(2)随着中纬度区域的缩小，其数量有增加的趋势。(3)随着中纬度地区水深（大气厚度）的增加，其数量有减少的趋势。(4)中纬度地区水深持续变化时，西风波随西风波形态和次数的变化而流动。(5)当北极地区受北极涛动影响较大时，其数量有减少的趋势。(6)北极振荡出现时西风波流动。(7)西风波在突出区顶部附近消失，在突出区通过后产生新的涡。

In this research using the Earth-model experiment apparatus, the following experimental results on the number of the meandering waves are obtained.(1) The number tends to decrease with the temperature increasing in the middle latitude region.(2) The number tends to increase with narrowing the middle latitude region.(3) The number tends to decrease with increase of the water depth(the atmospheric thickness) of the middle latitude area.(4) When the water depth of the middle latitude area changed continually, it is seen that the westerly wave flowed with the change of the form and the number of the westerly wave.(5) The number tends to decrease when the North Pole area protruded greatly by the arctic-oscillation.(6) The westerly wave flows when the arctic-oscillation is appeared.(7) The westerly wave disappears in the neighborhood of top of the protruding area, and a new vortex is generated after the passage in the protruding area.
