This dataset provides regional indices for Convectively Coupled Waves (CCWs) over South America. The indices include data on wave activity a covering a specified temporal and spatial range. The data is valuable for researchers studying the influence of CCWs on regional climate and weather patterns. Keywords: South American Regional Indices, Convectively Coupled Waves, Climate Data, CCWs Indices Data Description: Content: Includes indices for CCWs and time series data. Format: Available in text and NetCDF format. Coverage: Temporal coverage from 1979 to 2023 spatial coverage includes tropical South America domain. Methodology: The indices are derived using EOF analisysis after filtering OLR. Usage: The data can be used to analyze the seasonal and interannual variability of CCWs and their impact on South American weather patterns. Example applications include climate modeling, weather prediction, and atmospheric research.
