Nonlinear Trends and Non-Stationary Oscillations as Extracted from Annual Accumulated Precipitation at Mexico City
Extracted nonstationary oscillations and nonlinear trends of precipitation and sea surface temperature (SST) data reveal that rainfall variability in Mexico City is mainly composed by a long‐term positive trend, a multidecadal oscillation highly correlated with the Atlantic Multidecadal Oscillation...
