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 کاملMidnight temperature maximum (MTM) in Whole Atmosphere Model (WAM) simulations
[1] Discovered almost four decades ago, the midnight temperature maximum (MTM) with typical magnitudes of 50–100 K has been regularly observed by satellite and ground-based instruments in the tropical upper thermosphere. Although several mechanisms have been suggested to explain the phenomenon, previous attempts to reproduce it with comprehensive thermosphere-ionosphere models have been unsucce...
متن کاملThe midnight temperature maximum from Arecibo incoherent scatter radar ion temperature measurements
The midnight temperature maximum (MTM) is studied using ion temperature data from the incoherent scatter radar at the Arecibo Observatory (18.31N, 66.21W). The MTM is characterized by fitting the radar data with a function that takes into account diurnal, semidiurnal and terdiurnal components. Under the hypothesis that the MTM is related to the amplification of the terdiurnal wave, a Gaussian a...
متن کاملChagas disease transmission in periurban communities of Arequipa, Peru.
BACKGROUND Chagas disease, caused by Trypanosoma cruzi infection, is an urban problem in Arequipa, Peru, and the epidemiology of Chagas disease is likely to be quite different in this area, compared with in rural zones. METHODS We conducted a serosurvey of 1615 children <18 years old in periurban districts that included hillside shantytowns and slightly more affluent low-lying communities. In...
متن کاملPeriurban Trypanosoma cruzi–infected Triatoma infestans, Arequipa, Peru
In Arequipa, Peru, vectorborne transmission of Chagas disease by Triatoma infestans has become an urban problem. We conducted an entomologic survey in a periurban community of Arequipa to identify risk factors for triatomine infestation and determinants of vector population densities. Of 374 households surveyed, triatomines were collected from 194 (52%), and Trypanosoma cruzi-carrying triatomin...
