Present-day warm pool constrains future tropical precipitation

چکیده
Abstract Future changes in tropical precipitation affect the livelihood of world’s human population and ecosystems. Climate models project an increased rainfall intensification under anthropogenic warming, but uncertainties distribution magnitude remain large. Here, we identify a strong positive relationship between present-day Indo-Pacific warm pool size projected central-to-eastern Pacific using multi-model simulations. Models with larger excessive future warming eastern due to intensified ocean stratification which reduces zonal sea surface temperature gradient Pacific, resulting weakening Walker circulation increases Pacific. Based on this relationship, uncertainty can be reduced by approximately 25%, demonstrates that improved simulation is important for reliable projections.

A Further Study of the Tropical Western Hemisphere Warm Pool
Variability of the tropical Western Hemisphere warm pool (WHWP) of water warmer than 28.58C, which extends seasonally over parts of the eastern North Pacific, the Gulf of Mexico, the Caribbean, and the western tropical North Atlantic (TNA), was previously studied by Wang and Enfield using the da Silva data from 1945–93. Using additional datasets of the NCEP–NCAR reanalysis field and the NCEP SS...
متن کاملTropical western Pacific warm pool and maritime continent precipitation rates and their contrasting relationships with the Walker Circulation
[1] The Cenozoic reorganization of islands in the Maritime Continent region of the tropical western Pacific may have increased the amount of land surface area, changed the distribution of sea surface temperature (SST), and consequently provided a necessary condition for the onset of the Walker Circulation. Precipitation rates over the Maritime Continent, measured with the Tropical Rainfall Meas...
