 - very fast inference compared to typical physics-based atmospheric models
 
 Some known weaknesses are:
-- responses to El Niño-like sea surface temperature and long-term warming trends are not accurately captured
+- responses to El Niño-like sea surface temperature variability and long-term warming trends are not accurately captured
 - small but non-zero drifts in total dry air mass of the atmosphere
