This MJO in response is something else and we can see the response in the tropical […]
The super strong MJO crossing the Pacific Ocean has the ‘conga line’ of topical trouble steaming westward full throttle. The first two systems threaten China with the second (Chan hom) potentially a major hit near Shanghai. The powerful MJO is likely down to the extremely warm waters covering a large part of the Pacific at the moment. The […]
