In this study, the influence of the East Atlantic/Western Russia teleconnection pattern on the hydroclimatology of Europe, from mid-winter to late spring, is investigated. The influence of EAWR on the variability of precipitation (PP), temperature (TT) and standardized precipitation-evapotranspiration index (SPEI) is investigated on the base of correlation and stability maps. It is shown that E...

The impacts of four teleconnection patterns on atmospheric circulation components over Eurasia and the Pacific region, from low to high latitudes in the Northern Hemisphere (NH), were investigated comprehensively in this study. The patterns, as identified by the Climate Prediction Center (USA), were the East Atlantic (EA), East Atlantic/ Western Russia (EAWR), Polar/Eurasia (POLEUR), and Scandi...

Teleconnection patterns are one of the key features to understanding high-frequency natural climate variability. The North Sea-Caspian Pattern (NCP) was identified as a middle tropospheric dipole and its hydroclimatological implications have been substantially restricted Eastern Mediterranean region. Thus, influences NCP in Euro-Mediterranean region were investigated via comparative approach wi...

Abstract. This work presents a new, very long snowfall time series collected in remote site of Italian Apennine mountains (Montevergine Observatory, 1280 m above sea level). After careful check, based on quality control tests and homogenization procedures, the available data (i.e. daily height new snow) have been aggregated over winter season (December–February) to study long-term variability f...

Abstract Climatic changes in the atmosphere from Earth’s level to altitude of 80 km Russia and Republic Belarus (RB) are considered using data 1251 stations RIHMI-WDC (1976-2019), ERA5 reanalysis (1979-2019), 99 long-row located European part (ER) (RB). An analysis constructed trends air temperature (AT) atmospheric precipitation is made assess spatial temporal variability thermal humidity regi...

GloSea5, a seasonal forecast system of the UK Met Office, shows reasonable skill among state-of-the-art operational systems. However, average surface temperature (T2m) in winter (December–February) GloSea5 is particularly low East Asia. To improve over Asia, we focused on high score global teleconnection patterns simulated by GloSea5. Among well-predicted patterns, selected those highly correla...

In this study, we investigate the dominant modes of surface air temperature variations cold season (from November through to next March) and warm May September) over Central Asia, their associations with large-scale climate patterns for period 1979–2016. The first two (CSAT) obtained by empirical orthogonal function (EOF) analysis, feature monopole structure north-south dipole pattern, respecti...

drought, as a normal, recurrent climatic condition with complicated mechanism, is one of the least known natural disasters that may occur in any climatic condition. considering the recent drought events in the iran and the deterioration of water crisis, especially in the area under study, the necessity of further research in this area is felt. also, the evaluation and monitoring of drought with...

Teleconnection patterns affect the weather and climate on both interannual decadal timescales which in turn affects various socio-economic sectors such as agriculture. We use three indices based E-OBS data from INDECIS dataset (growing season onset [ogs10], growing rainfall [gsr] temperature [ta_o]) to assess variability trends over 1950–2017 associated with four teleconnection (North Atlantic ...
