I ordered the topics in some loose combination of relevance to current research, and the time and effort I have put into them. I do not include some recent interests (Western US rainfall, Pacific cold tongue dynamics) that are still in early stages.
The descriptions are somewhat wordy, but I want to convey the situation and thinking that led me down these paths. Most research topics arose serendipitously: chancing on a paper or a talk that caught my interest, or a conversation with a colleague.
Some ideas caught on quickly, like the ITCZ shifts. Others took longer - the Pacific Meridional Mode languished for years before gaining wider acceptance. I’m still waiting on takers for the Split Jet idea. I don’t mind - it allows for more time to develop them.
