| 英文摘要: | This study examines the spatial and temporal surface (10 m) wind speed trend characteristics of Brazil during 1980–2014 using two in situ and three climate reanalysis datasets. Nonparametric regression is used to understand how mean seasonal and annual wind speeds change over space and time across Brazil. Overall temporal linear trends show that station and reanalysis products exhibit varying seasonal and annual wind speed trends. A geographic examination displays statistically significant (P < 0.05) positive (negative) mean wind speed trends for equatorial (southeastern and central) Brazil. Quantile regression is performed to interpret how wind speed changed across different percentiles. Results show that the largest positive and negative spatial wind speed trends occur for the upper percentiles (75 and 95%). The spatial and temporal trends and correlations described could be interconnected to possible changes developing with the location of Intertropical Convergence Zone and South Atlantic Anticyclone over the study region. Results have implications for optimizing renewable wind energy production and development across Brazil. © 2017 Royal Meteorological Society |
