INFRASONIC EFFECT OF SOLAR ECLIPSES
The relevance of this study is due to the need to understandphysical effects associated with rare phenomenon, solar eclipse.Until recently, the features of internal gravity wave generationhave been studied in the 10 −100 min period range, while in thisstudy an attempt is made to confirm the fact of...

| description | The relevance of this study is due to the need to understandphysical effects associated with rare phenomenon, solar eclipse.Until recently, the features of internal gravity wave generationhave been studied in the 10 −100 min period range, while in thisstudy an attempt is made to confirm the fact of generationand estimate the general parameters of infrasound oscillationsassociated with solar eclipses in the 1−10 min period range.The observations were made with the HF Doppler radar at verticalincidence. The data were subjected to spectral analysis andband-pass filtering. The solar eclipses that had occurred overKharkiv city (Ukraine) within 1999–2011 are determined to beassociated with Doppler shift of frequency oscillations in theinfrasound frequency band (~ 5−8 min period range) and withamplitude of 20 −100 mHz. The corresponding amplitudeof electron density oscillations was approximately equal to0.1− 0.5 %. |

Актуальность работы обусловлена необходимостью исследования физических эффектов, сопровождающих редкое природ-ное явление – солнечное затмение. До настоящего времени исследовались особенности генерации солнечным затмениемвнутренних гравитационных волн в атмосфере с периодами T ~ 10÷ 100 мин. В представленной работе предпринятапопытка подтвердить факт генерации и оценить основные параметры инфразвуковых колебаний с T~1÷10 мин, сопро-вождавших солнечные затмения. Для наблюдений использовался доплеровский ВЧ радар вертикального зондирования.Для обработки данных применялся спектральный анализ и полосно-пропускающая фильтрация. Подтверждено, чточастные солнечные затмения, имевшие место над Харьковом (Украина) в 1999–2011 гг., как правило, сопровождалиськолебаниями доплеровского смещения частоты инфразвукового диапазона (T ~ 5÷ 8 мин) и амплитудой 20÷ 100 мГц.Им соответствовала относительная амплитуда колебаний концентрации электронов около 0.1÷ 0.5% Видавничий дім «Академперіодика» 2013-07-03 Article Article application/pdf http://rpra-journal.org.ua/index.php/ra/article/view/1128 РАДИОФИЗИКА И РАДИОАСТРОНОМИЯ; Vol 18, No 2 (2013); 127 RADIO PHYSICS AND RADIO ASTRONOMY; Vol 18, No 2 (2013); 127 РАДІОФІЗИКА І РАДІОАСТРОНОМІЯ; Vol 18, No 2 (2013); 127 2415-7007 1027-9636 ru http://rpra-journal.org.ua/index.php/ra/article/view/1128/765 |
