Skewness modes in the Northern Hemisphere winter
The probability distribution of daily Northern Hemisphere streamfunction fluctuations at 500 hPa in winter is skewed at most locations. Large positive anomalies are more likely north of 50N with maximum values of the skewness in the North Pacific and North Atlantic region. In this study we develop two novel methodologies in order to diagnose the underlying circulation structures associated with...
متن کاملSolar forcing of winter climate variability in the Northern Hemisphere
An influence of solar irradiance variations on Earth’s surface climate has been repeatedly suggested, based on correlations between solar variability and meteorological variables1. Specifically, weaker westerly winds have been observed in winters with a less active sun, for example at the minimum phase of the 11-year sunspot cycle2–4. With some possible exceptions5,6, it has proved difficult fo...
متن کاملDynamical Mechanisms for the Teleconnection between ENSO and NAO in Late Winter
The dynamical mechanisms for the late-winter teleconnection between El NiñoSouthern Oscillation (ENSO) and the North Atlantic Oscillation (NAO) are examined using output from two global climate models and various reanalysis datasets. During El Niño winters, the intensified transient disturbances along the equatorward shifted North Pacific storm track extend their influences farther downstream, ...
متن کاملInfluences of ENSO SST Anomalies and Winter Storm Tracks on the Interannual Variability of Upper-Troposphere Water Vapor over the Northern Hemisphere Extratropics
This study examines the interannual variability of winter upper-troposphere water vapor over the Northern Hemisphere using the National Aeronautics and Space Administration Water Vapor Project, the International Satellite Cloud Climatology Project data, and the European Centre for Medium-Range Weather Forecasting reanalysis. The El Niño–Southern Oscillation related tropical sea surface temperat...
متن کاملEurasian snow cover, more skillful in predicting U.S. winter climate than the NAO/AO?
[1] Successfully predicting the phase and strength of the dominant winter mode of variability for the Northern Hemisphere (NAO/AO) is considered the most important future breakthrough in winter climate prediction; however skillful prediction of the index has been elusive. In this Letter we present a snow index constructed from observed summer and fall anomalies that is more highly correlated th...
