Abstract

We have investigated 49 solar macrospicules observed in 2010 at the rising phase of the solar cycle at high (circumpolar) and low (near the solar equator) latitudes. We have found that, within the measurement accuracy, the macrospicule birth rate does not depend on the latitude and is \({\sim}0.1\) deg\({}^{-2}\) h\({}^{-1}\). Concurrently, we have established that the mean heights of macrospicules near the equator and the poles differ noticeably. After the elimination of projection effects, we have obtained \(31.7\pm 0.2\) thousand km for macrospicules at low latitudes and \(39.1\pm 0.3\) thousand km for high-latitude macrospicules.

低纬度和高纬度地区太阳大针状体特征的差异

我们研究了2010年在高纬度（环极）和低纬度（靠近太阳赤道）太阳周期上升期观测到的49个太阳宏观粒子。我们发现，在测量精度范围内，巨大儿出生率不取决于纬度，为（｛\sim｝0.1\）deg\（｛｝^｛-2｝）h\（｝^｝-1｝）。同时，我们已经确定，赤道和两极附近的宏观小丘的平均高度明显不同。在消除投影效应后，我们获得了低纬度宏观小天体的\（31.7\pm 0.2）千公里和高纬度宏观小卫星的\（39.1\pm 0.3）千公里。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
