At least that is how I use the terms. :-) Not a major issue - I have the same type of comment when writers use "resolution" in a model when they really mean "grid increment".

During this time both the GMST anomalies and the OHC anomalies went up. It is not until GMST anomalies start dropping as the El Nino weakened that this drop in OHC occurs. So am I wrong to think some of the loss in 0 to 2000 meter OHC was to the deeper ocean and not just to the atmosphere?Anonymousnoreply@blogger.com
