The relation between ionosonde critical frequency of ionospheric sporadic E-layer ($f_o{E}_s$) and disturbed zonal wind is studied over Okinawa (26.68°N, 128.15°E), Rome (41.98°N, 12.49°E) and Townsville (19.63°S, 146.8°E) during different solar activity years, 1987 (moderate), 1996 (low) & 2001 (high) (Okinawa and Townsville) and 1987 (moderate), 1995 (low) & 2000 (high) (Rome). The variation of monthly hourly medians of $f_o{E}_s$ shows annual trend with maximum values in local summer. However, it does not show dependence on solar activity. The correlation is studied between median $f_o{E}_s$ values and the zonal winds obtained from climatological Horizontal Wind Model (HWM14). The strong correlation coefficients obtained between the parameters suggest that HWM14 may be used as a proxy to predict the climatology of the sporadic layers. A more comprehensive study based upon the same procedure is planned in future.

电离层零星E层电离探空仪临界频率之间的关系($F_{○}{乙}_{秒}$) 和扰动纬向风研究了冲绳 (26.68°N, 128.15°E)、罗马 (41.98°N, 12.49°E) 和汤斯维尔 (19.63°S, 146.8°E) 在不同的太阳活动年份, 1987 (中等) 、1996（低）和 2001（高）（冲绳和汤斯维尔）和 1987（中等）、1995（低）和 2000（高）（罗马）。每月每小时中位数的变化$F_{○}{乙}_{秒}$显示在当地夏季具有最大值的年度趋势。然而，它没有表现出对太阳活动的依赖。研究中位数之间的相关性$F_{○}{乙}_{秒}$值和从气候水平风模型 (HWM14) 获得的纬向风。参数之间获得的强相关系数表明 HWM14 可以用作预测零星层气候学的代理。未来计划基于相同程序进行更全面的研究。
