Abstract: he Pacific?North American (PNA) teleconnection is a major mode of Northern Hemisphere wintertime climate variability, with well-known impacts on North American temperature and precipitation. To assess whether the PNA ...

Abstract: he 2013/14 boreal winter (December 2013?February 2014) brought extended periods of anomalously cold weather to central and eastern North America. The authors show that a leading pattern of extratropical variability, whose ...

Abstract: ariability of springtime tornadic activity over the United States is assessed through the connectivity of preferred modes of North American low-level jet (NALLJ) variability to the local thermodynamic environment and remote ...

Abstract: agged pentad composites of surface air temperature and precipitation are analyzed for the winter season (December?February) to assess the influence of the Madden?Julian oscillation (MJO) on the climate of the contiguous ...

Abstract: he Pacific/North American (PNA) pattern, North Atlantic Oscillation (NAO), and Arctic Oscillation (AO) are three dominant teleconnection patterns known to strongly affect December-February surface weather in the Northern ...
