Modeled changes to the Great Plains low-level jet under a realistic irrigation application.

Atmos Sci Lett 2019 Mar 28;20(3):e888. Epub 2019 Feb 28.

Department of Geography, Environment, and Spatial Sciences Michigan State University East Lansing Michigan.

Low-level jets (LLJs) are relatively fast-moving streams of air that form in the lower troposphere and are a common phenomenon across the Great Plains (GP) of the United States. LLJs play an important role in moisture transport and the development of nocturnal convection in the spring and summer. Alterations to surface moisture and energy fluxes can influence the planetary boundary layer (PBL) development and thus LLJs. Read More

Connections between the Madden-Julian Oscillation and surface temperatures in winter 2018 over eastern North America.

Atmos Sci Lett 2019 Jan 19;20(1):e869. Epub 2018 Nov 19.

Oceanography Department U.S. Naval Academy Annapolis Maryland.

From January to March 2018, one of the strongest Madden-Julian Oscillation (MJO) events of the last 45 years progressed eastward along the equator from the Indian Ocean to the Pacific Ocean then back to the Indian Ocean. In response to strong tropospheric heating in the MJO's active convective envelope, several pronounced Rossby wave trains developed and extended from the equatorial tropics, across the extratropical Pacific and North America, and into the extratropical Atlantic. The origins of these Rossby wave trains evolved eastward with time, generally following the eastward progression of the MJO, but preferentially clustered in subtropical India and Southeast Asia and in two locations in the subtropical Pacific Ocean: along 160°E and 170°W.

Predictability of European winter 2016/2017.

Atmos Sci Lett 2018 Dec 4;19(12):e868. Epub 2018 Nov 4.

Met Office Hadley Centre Exeter UK.

Winter 2016/2017 was one of the driest on record for central Europe and the United Kingdom. This was the result of blocked atmospheric circulation with high pressure centred over North-West Europe dominating the winter mean circulation pattern. Using large ensembles of simulated winters, we find that the observed winter 2016/2017 circulation was very similar in pattern and strength to the circulation associated with the top 10% of driest Central European winters.
