The Earth close approach of near-Earth asteroid 2005 LW3 on 2022 November 23 represented a good opportunity for a second observing campaign to test the timing accuracy of astrometric observation. With 82 participating stations, the International Aste

Tightening of tropical ascent and high clouds key to precipitation change in a warmer climate

Autor: Hui Su, Jonathan H. Jiang, J. David Neelin, T. Janice Shen, Chengxing Zhai, Qing Yue, Zhien Wang, Lei Huang, Yong-Sang Choi, Graeme L. Stephens, Yuk L. Yung

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-9 (2017)

The sensitivity of global precipitation to warming is largely governed by changes in atmospheric longwave radiation, a function of cloud cover. Here the authors show that tightening of the tropical circulation with warming drives a decrease in high c

Simulations of tropical atmospheric circulation response to surface warming vary substantially across models, causing large uncertainties in projections of regional precipitation change. Understanding the physical processes that drive the model sprea

In the search for exoplanets, one of the most sought-after goals from the outset has been to survey nearby systems for Earth-mass planets in their habitable zones. Because of their relatively low mass and size, and their separation from their host st

The Zwicky Transit Facility (ZTF) is a powerful time domain survey telescope with a large field of view of 47 deg 2 . We apply the synthetic tracking technique to integrate a ZTF’s deep drilling data set, which consists of 133 nominal 30 s exposure
