PCA and vTEC climatology at midnight over mid-latitude regions
The effect of the thermospheric vertical neutral wind on vertical total electron content (vTEC) variations including longitudinal anomaly, remaining winter anomaly, mid-latitude summer night anomaly, and semiannual anomaly is studied at mid-latitude regions around zero magnetic declination at midnight during high solar activity. By using the principal component analysis (PCA) numerical techniqu...
متن کاملEstimating the Response of Extreme Precipitation over Mid-latitude
Global warming induced changes in extreme orographic precipitation are investigated using a hierarchy of models: a global climate model, a limitedarea weather forecast model, and a linear mountain-wave model. We consider precipitation changes over an idealized north-south mid-latitude mountain barrier at the western margin of an otherwise flat continent. The intensities of the extreme events on...
متن کاملThe role of ionospheric clutter in mid-latitude and arctic regions for assessment of HFSWR surveillance
The ionosphere is the region of the earth’s atmosphere in which gases are ionized by radiation such as ultraviolet light from the sun and cosmic rays from outer space. The unwanted radar echoes from the ionosphere are collectively called ionospheric clutter. This paper studies the arctic and mid-latitude ionospheric environment using ionosonde data and assesses High-Frequency Surface-Wave Radar...
متن کاملUltraviolet climatology over Argentina
[1] Satellite-derived climatologies of UV index (UVI) and erythemal daily dose were determined for Argentina at a geographical resolution of 0.5 latitude by 0.5 longitude. Total Ozone Mapping Spectrometer climatology of key input parameters was used to calculate the clear-sky ground-level solar UV irradiance. NASA Surface meteorology and Solar Energy cloud cover data were used to determine the ...
