В предположении о том, что ход времени изменился в ограниченной области пространства у поверхности Земли, анализируется взрывоопасность такого события.</p><p>Объект и основы метода исследования. В сферически симметричной постановке задачи исследовали возмущения идеального газа (воздуха), вызванные изменением хода времени (на относительную величину θ порядка ±10–12) в неподвижной области пространства. Решение задачи основывается на предположении о правомерности модификации известной зависимости показаний часов от расположения часов в ускоренно движущейся системе отсчета (Einstein, 1907), когда ускорение (причина) и изменение хода времени (следствие) переставлены местами.</p><p>Результаты и их обсуждение. В зоне изменения хода времени возникает поле ускорения, которое по своему воздействию на воздух аналогично гравитационному полю. Приграничная область зоны выполняет роль «насоса», качающего в зону окружающий воздух или выбрасывающего воздух из зоны в случае θ &lt; 0 или θ &gt; 0 соответственно. При этом давление и температура воздуха в зоне соответственно увеличиваются или уменьшаются в некоторых случаях на порядки.</p><p>Косвенная проверка результатов. Осуществлялась путем применения полученных результатов к описанию вихревого движения и шаровой молнии.</p></sec><sec><title>Выводы</title><p>Выводы. Введен безразмерный параметр θ, выражающий локальное возмущение (изменение) хода времени по отношению к ходу времени в остальном пространстве, где θ = 0. Предложена модель исследования изменения параметров атмосферы в зоне, где θ ≠ 0. Выполнены оценки экстремальных значений параметров состояния воздуха в зоне для случаев уменьшения (θ &lt; 0) и увеличения (θ &gt; 0) хода времени. Для случая θ &lt; 0 релаксация флуктуации хода времени (θ → 0) может сопровождаться взрывом. Модель с θ &gt; 0 может использоваться при объяснении свечения шаровой молнии, исчезающей без взрыва.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Assuming that the course of time has changed in a limited area of space near the Earth’s surface, the explosiveness of such an event is analyzed. </p><p>The object and foundations of the research method. In a spherically symmetric formulation of the problem, perturbations of an ideal gas (air) caused by a change in the course of time (by a relative magnitude θ of the order of ±10–12) in a stationary region of space were investigated. The solution of the problem is based on the assumption that it is legitimate to modify the known dependence of the clock readings on the location of the clock in an accelerated moving reference frame (Einstein, 1907), when the acceleration (cause) and the change in time course (effect) are permuted.</p><p>The results and their discussion. In the zone of time course change, a field acceleration series, which, in its effect on the air, is similar to the gravitational field. The boundary area of the zone acts as a “pump”, pumping ambient air into the zone or ejecting it from the zone in case of θ &lt; 0 or θ &gt; 0, respectively. At the same time, the air pressure and temperature in the zone respectively increase or decrease, in some cases, by orders of magnitude. </p><p>Indirect verification of results. It is made by applying the obtained results to the description of vortex motion and ball lightning.</p></sec><sec><title>Conclusions</title><p>Conclusions. A dimensionless parameter θ is introduced, expressing a local perturbation (change) of time course in relation to the time course in the rest of space, where θ = 0. A model is proposed for studying changes in atmospheric parameters in a zone where θ ≠ 0. The estimates of the extreme values of the parameters of the air condition in the zone for the cases of time course decrease (θ &lt; 0) and increase (θ &gt; 0) are performed. For the case θ &lt; 0, the relaxation of the time course fluctuation (θ → 0) can be accompanied by an explosion. The model with θ &gt; 0 can be used to explain the glow of a ball lightning that disappears without an explosion.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>управление ходом времени</kwd><kwd>поле ускорения</kwd><kwd>закон сохранения энергии</kwd><kwd>шаровая молния</kwd></kwd-group><kwd-group xml:lang="en"><kwd>time course control</kwd><kwd>acceleration field</kwd><kwd>conservation energy law</kwd><kwd>ball lightning</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Einstein A.
