Exact premise of my winter forecast. This blocking is not characteristic of major east-based El Nino events, which is the difference I kept harping on. Yes, the -PDO is similar to some of them, which is acknowledged. There are years with both, such as 1965-1966, which is a great analog.
This was clear to me last summer.
