Extreme climate and weather events are unusual rare that often cause a lot of damage both to nature people. They take place in the air (storms, tornadoes, heavy rain, atmospheric rivers), ocean (storm surges, marine heatwaves), on land (wildfires, heatwaves, floods, droughts). Many extremes happen naturally, even without change. But Earth’s changing does change where how some extreme place, strong those are. What events? Will new or stronger due change? How is impacting These type questions...
Abstract. The Arctic is warming faster than the global average and any other region of a similar size. One important factor in this poleward atmospheric transport heat moisture, which contributes directly to surface air warming. In case study, circulation spatio-temporal structure moisture intrusion event assessed, occurred from 5 7 June 2017 over Nordic seas during an intensive measurement campaign Svalbard. This analysis focuses on high-spatial-resolution simulations with ICON (ICOsahedral...
Abstract Polar lows (PLs) are small, intense cyclones that form at high latitudes during the winter. Their wind speeds and heavy precipitation can have substantial impacts on shipping, coastal communities infrastructure. However, low‐resolution climate models poorly simulate PLs, which reduces confidence in their future projections. In this study, Northern Hemisphere (NH) PLs assessed for first time a high‐resolution (25 km) global atmosphere‐only model, N512 HadGEM3‐GA3, both present‐day...

<p>The Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) is largest one-year-long research expedition within central and has started in September 2019 to gather comprehensive climate data from an almost unreachable region. The gathered observational combination with concurrent high-resolution modeling provide new insights that play a key role improvement our understanding interaction processes between atmosphere, ocean, sea ice eventually global...

<p>Understanding the variability of energy transport and its components, mechanisms involved, is critical to improve our understanding Arctic amplification. Large amounts are transported from equator poles by large-scale atmospheric circulation. At Circle, this represents an annual average net about two PW. The can be divided into latent dry static components which, when increasing, indirectly contribute While enhanced favors sea ice melt changes lapse rate, influx affects...
