This article examines the influence of permanent center atmospheric action - Arctic anticyclone (Arctic High) on dynamics adjacent circulating oscillatory structures North Atlantic. Analysis variance was used to estimate degree state centers atmosphere in The High change pressure Icelandic minimum and Azores maximum is estimated at 48%. showed not statistical significance, confirmed by Fisher's...
Understanding and predicting the state of North Atlantic Oscillation (NAO) is key to forecasting weather in United Kingdom (UK). It has been shown that particular phases Madden–Julian (MJO) act as precursors either NAO+ or NAO? events. We assess ability UK Met Office coupled climate model (HadGEM3-GC3.1-MM) simulate these NAO responses at lead times 1–2 weeks show improvements are needed modell...

introduction long-term annual extreme climate events, especially temperature and precipitation, have generally been used as indicators for the assessment of climate change. one of the most changeable climatic variables in time and space is precipitation. there are great number of research papers focusing on extreme precipitation on global, regional and national scales have been written. the res...
[1] The surface response to 11 year solar cycle variations is investigated by analyzing the long-term mean sea level pressure and sea surface temperature observations for the period 1870–2010. The analysis reveals a statistically significant 11 year solar signal over Europe, and the North Atlantic provided that the data are lagged by a few years. The delayed signal resembles the positive phase ...
The Atlantic Multidecadal Oscillation (AMO) has pronounced influences on weather and climate across the globe. This study provides a direct comparison of the observed AMO-related surface temperature and precipitation anomalies to those simulated in the Coupled Model Intercomparison Project Phase 5 (CMIP5) models. It is found that the model-simulated AMO-related features are obscured by the glob...
