Nino and Nina compared. Nino seasons have deep consequences in rain amounts. And with all the talk about the forecasted Super-El Nino, I wanted to know what the differences were. You too? Here you go. Maps show seasonal differences between Nino and Nina anomalies. The first image shows rain data from #GHCN weather stations and sea surface temperature from ErsstV6. The second image shows tmax from the weather stations and sst. The underlying data are anomalies over 30-year running averages from 1870-2025, but computed as percent which makes plotting and merging different units in Panoply easy. After the monthly anomalies were computed, the data got split into Nino and Nina months and seasons. Made with https://www.giss.nasa.gov/tools/panoply/ using data from https://www.ncei.noaa.gov/data/sea-surface-temperature-extended-reconstructed/v6/access/ and GHCNdaily https://www.ncei.noaa.gov/pub/data/ghcn/daily/
