Weak Bidirectional Outflows and Flare Current Sheet in a Solar Coronal Jet Driven by the Eruption of a Minifilament by Jiayan Yang, Junchao Hong, Bo Yang, Yi Bi, Zhe Xu

“…With the excellent data of the Solar Dynamics Observatory, we present the observational signatures of these two magnetic reconnection processes during a solar coronal jet that occurred in a huge coronal hole of northern hemisphere. The jet was triggered by the eruption of a minifilament that located at a coronal bright point in the coronal hole. …”

Detection of Carbon Use Efficiency Extremes and Analysis of Their Forming Climatic Conditions on a Global Scale Using a Remote Sensing-Based Model by Miaomiao Wang, Jian Zhao, Shaoqiang Wang

“…We found grasslands have the largest potential in changing global CUE, with the contribution being approximately 32.4% to positive extremes and 30.2% to negative extremes. Spring in the Northern Hemisphere (MAM) contributed the most (30.5%) to positive CUE extremes, and summer (JJA) contributed the most (29.7%) to negative CUE extremes. …”

Performance of Solar Control Films on Building Glazing: A Literature Review by Júlia Pereira, Henriqueta Teixeira, Maria da Glória Gomes, António Moret Rodrigues

“…The presence of SCFs significantly reduced indoor solar radiation and illuminance levels, particularly with reflective films applied to south-oriented glazing (northern hemisphere). Glazing systems with SCFs were reported to promote cooling energy savings compared with clear glazing in hot climates. …”

Secular trend of global drought since 1950 by Xiaodong Song, Yu Song, Yuanyuan Chen

“…We suggested that there was an accelerated drying trend over global land surface as a whole, but large areas with wetting trend existed in the meantime, especially at the high latitudes in the northern hemisphere. Additionally, we found that the PDSI secular trend change rate exhibits a multidecadal variability of about 50 years or so and it implies a potential relationship with periodic variations of the oceanic and atmospheric current. …”

Short periodic variations of polar motion and hemispheric atmospheric angular momentum excitation functions in the period 1984-1992 by J. Nastula

“…The strong short periodic variation of the length of day (&lt;i&gt;LOD&lt;/i&gt;) and &amp;#x03C7;&lt;sub&gt;&lt;i&gt;y&lt;/i&gt;&lt;/sub&gt; in the early 1988 seems to be caused by the above-mentioned 35-55 days oscillations of the northern hemisphere atmosphere. This variation can be related to the rapid passing from the El Niño to the La Niña phenomenon or from the minimum to the maximum in the Southern Oscillation Index in 1987-1989.…”
