AI 中文摘要
D区电离层在响应入射太阳辐射时本质上是迟缓的。我们研究了所选三次太阳耀斑(即C5.2、M5.2和X2.2级)期间中纬度D区响应时间延迟(Delta t)的高度(h)剖面。我们在每个高度上数值求解“电子连续性方程”,以获得Delta t-h剖面。我们分别研究了这些太阳耀斑中每一个的Delta t-h剖面的1)纬度变化(北半球和南半球)和2)季节变化(全年)。我们考察了1)和2)的Delta t-h剖面的显著变化,在不同半球上得到了相当不同的结果。此外,我们研究了X2.2级耀斑的Delta t-h剖面在1)和2)方面与C5.2或M5.2级耀斑相比的一些对比行为。我们以可能的解释来总结结果。
英文摘要
The D-region ionosphere is sluggish in nature while responding to the incoming solar radiation. We study the altitude (h) profile of mid-latitude D-region response time delay (Delta t) during three chosen solar flares, namely, C5.2, M5.2, and X2.2 classes. We solve "electron continuity equation" numerically at each and every h to obtain Delta t-h profile. We investigate the 1) latitudinal variation (over both Northern and Southern hemispheres) and 2) seasonal variation (throughout the year) of Delta t-h profiles of each of these solar flares separately. We go over noteworthy variations of Delta t-h profile for both 1) and 2) with reasonably different results over different hemispheres. Also, we study some contrasting behaviours of Delta t-h profile of X2.2 class for both 1) and 2) in comparison to C5.2 or M5.2 classes. We conclude the outcome with possible explanations.
