چکیده

Abstract This study investigates the centennial-scale (i.e., since 1926) variability of observed near-surface wind speed across Sweden. Results show that underwent various phases change during 1926–2019, i.e., (a) a clear slowdown 1926–1960; (b) stabilization from 1960 to 1990; (c) another 1990–2003; (d) slight recovery/stabilization period for 2003–2014, which may continue with possible new slowdown. Furthermore, performance three reanalysis products in representing past variations is evaluated. The low-frequency properly simulated by selected reanalyses and linked different large-scale atmospheric circulation patterns (e.g., North Atlantic Oscillation). However, evident periods decreasing trend 1926–1960 1990–2003, drive most stilling last century, are missing cannot be realistically modeled through multiple linear regression only using indexes circulation. Therefore, this reveals changes mainly speed, while other factors surface roughness) crucial explaining strong terrestrial

Study of the models of large-scale atmospheric circulation system model on intesify rainfall in Ardebil plain

Atmospheric circulation is important to determine the surface climate and environment, and affect regional climate and surface features. In this study, to quantify its effect, the classification system, developed by Lamb is applied to obtain circulation information for Ardabil, North West Province in Iran, on a daily basis, and is a method to classify synoptic weather for study area. For that p...

Observed Coherent Trends of Surface and Upper-Air Wind Speed over China since 1960

Previous studies indicated that surface wind speed over China declined during past decades, and several explanations exist in the literature. This study presents long-term (1960–2009) changes of both surface and upper-air wind speeds over China and addresses observed evidence to interpret these changes. It is found that surface wind over China underwent a three-phase change over the past 50 yr:...
