HIGH-LATITUDE THERMOSPHERIC ZONAL WINDS DURING PERIODS OF LOW SOLAR ACTIVITY
Ummu Abiola , Department of Physics and Astronomy, University of Nigeria, Nsukka, Enugu State, NigeriaAbstract
This study investigates the behavior and characteristics of high-latitude thermospheric zonal winds during periods of low solar activity. Utilizing data from satellite observations and ground-based instruments, we analyze the variations in zonal wind patterns at high latitudes and their correlation with reduced solar activity levels. Our findings indicate significant alterations in wind speed and direction, highlighting the impact of diminished solar radiation on atmospheric dynamics. The study also explores the underlying mechanisms driving these changes, including the influence of geomagnetic activity and ionospheric conditions. The results contribute to a better understanding of the thermospheric response to solar activity variations, offering insights into the complex interactions between solar radiation and Earth's upper atmosphere. These findings have important implications for satellite operations, communication systems, and our broader understanding of space weather phenomena during solar minima.
