摘要

2021年6月10日的日食是环食,是Saros 147的一员。第一次接触发生在2021年6月10日08:12:20 UT,第四次接触发生在13:11:19 UT。最大东南风震级出现在世界时09:49:50 ~ 11:33:43。环行发生在世界时10:33:16到10:36:56之间。日食开始于加拿大境内。影子穿过格陵兰岛(日环食发生的地方)、北冰洋、北极、新西伯利亚岛和俄罗斯联邦。在蒙古、中国的大部分地区、美国东北部、阿拉斯加北部、整个北冰洋、北大西洋,以及乌克兰的大部分地区,除了敖德萨、尼古拉耶夫、赫尔松地区和克里米亚之外,都可以观测到这次日偏食。在这项工作中,描述了2021年6月10日在哈尔科夫市地面空气层中对东南风的热(温度)效应的观测;对1999-2021年同一地区发生的8次se的热效应进行了比较。对地面空气层影响的观测是在哈尔科夫附近的卡拉津国立大学辐射物理观测站进行的。用标准仪器测量空气温度、气压和湿度、风速和风向。测温精度为0.1℃。估算了日食的能量平衡。由于东南风的作用,地表大气中气体的内能降低了~5.3 × 1018 J,相当于平均功率为1.2 PW。比能和功率分别为6.5 kJ/m3和1.4 W/m3。在日食当天和参照日观测了地表大气温度的变化。这些数据与当时的对流层天气一起进行了分析。天气不利于观测日食的热效应。估计了日食最大星等期间的大气冷却;温度下降了大约1°C。不同季节、当地时间、云结构、地表状态和大气对流等因素可以解释8个SEs期间热效应的差异。

Thermal Effect in Surface Atmosphere of the Solar Eclipse on June 10, 2021

The solar eclipse (SE) on June 10, 2021, was annular and a member of Saros 147. The first contact occurred at 08:12:20 UT on June 10, 2021, and the fourth contact occurred at 13:11:19 UT. The maximal SE magnitude was observed from 09:49:50 to 11:33:43 UT. The annularity took place from 10:33:16 to 10:36:56 UT. The solar eclipse began over the territory of Canada. The shadow moved across Greenland (where the annularity took place), the Arctic Ocean, the North Pole, New Siberia Island, and the Russian Federation. The partial eclipse was observed in Mongolia, in a major part of China, in the northeast of the United States, in North Alaska, all over the Arctic Ocean, and in the North Atlantic, as well as over a major part of Ukraine, except for the Odessa, Nikolaev, and Kherson regions and Crimea. In this work, the observations of the thermal (temperature) effect of the SE of June 10, 2021, in the surface air layer in the city of Kharkiv are described; the thermal effects of eight SEs that occurred in the same region in 1999–2021 are compared. The observations of the effects in the surface air layer were made at Karazin National University Radiophysics Observatory, in the vicinity of Kharkiv. The air temperature, atmospheric pressure and humidity, and the wind speed and direction were measured with standard instrumentation. The temperature measurement accuracy was 0.1°C. The solar eclipse energy balance is estimated. The internal energy of gas in the surface atmosphere has been shown to decrease by ~5.3 × 1018 J due to the SE, which corresponds to an average power of 1.2 PW. The specific energy and power were 6.5 kJ/m3 and 1.4 W/m3. The variations in the air temperature of the surface atmosphere were observed during the day of the solar eclipse and on the reference days. They were analyzed along with the tropospheric weather for those days. The weather was not favorable for observations of the thermal effect of the eclipse. The atmospheric cooling occurring during the eclipse magnitude maximum is estimated; the decrease in the temperature amounted to approximately 1°C. The differences in the thermal effects during the eight SEs compared are explained by different seasons, local time, cloud structure, state of the Earth’s surface, and atmospheric convection.
