- •
Chaotic dynamics of precipitation and temperature from reanalyses are investigated.
- •
ERA-Interim closely replicates observed precipitation's chaotic dynamics.
- •
MERRA is superior in capturing the temperature's chaotic dynamics.
- •
Inaccurate representation of precipitation characteristics by the reanalysis products
- •
Reanalyses fail to replicate the abrupt temperature trends in the recent decades.
