In this dissertation, EISCAT radar observations and computer numerical simulation methods are involved to study the climatologic characteristics of polar ionosphere and their mechanisms, as well as the polar ionospheric responses to magnetospheric particle precipitation and convection electric field. Then, with the help of the numerical computation, the EISCAT data are employed to invert the energy spectra of auroral precipitating particles and their responses to magnetic storms and substorms.

As the beginning of this thesis, the important meanings of sea ice to global climate change and ocean engineering in polar and subpolar sea regions are explained firstly. Then, it is pointed out that sea ice numerical modelling, as a powerful tool of sea ice research, is limited by the precision of parameters within models instead of itself so far. It is meaningful to study the important parameters of sea ice dynamics by means of the rapidly developing digital imaging techniques so as to provide better input parameters needed in numerical models.

文中首先阐述了海冰对全球气候变化和极区、亚极区海域海洋工程问题的重要性，并指出作为海冰研究重要手段之一的海冰数值模拟发展到目前，其准确性更加受到海冰参数而非模式本身的限制，因此以目前快速发展的数字图像技术为工具对海冰动力学过程中的重要参数进行研究，以提供数值模式所需要的高精度和准确性的数据，是非常有必要的。

Although Taipei and Taichung are both basin landforms, the distribution of the heat island in Taichung is centered and distinct, while that of Taipei is large and of a wide variety because of its high development and urbanization It is also clear from the results that in urban areas, large greened areas or parks play a key role in reducing temperatures.

海岸地形的都会区，都市热岛现象受到海陆气候极大的影响，使得白天热岛中心偏向内陆，晚上热岛中心则偏向海边。虽然台中与台北同属盆地地形，但台北都会区因具有大范围、高度发展与复杂的商业、人为活动，而使得其都市热岛中心分布不像台中集中与明显。
