During the period from October through the second week of December, anomalously warm or near-normal temperatures persisted in most land regions around the globe except in the following few: northwest Africa, the Alaska, eastern USA and Mexico, Chile and several small pockets in South America, western Australia, the Middle East and several pockets in Asia; since December, most of Canada also is experiencing cooler than normal anomalies. In southern hemisphere, Australia and New Zealand received near-normal to slightly surplus rainfall; the signals in Australia actually shifted from dry in October to wet since November. Most of the nations in South America received near-normal to below normal rainfall. In general, near-normal to below normal rainfall was also observed in the northern hemisphere land regions. While the predictions were successful in capturing anomalous temperature (rainfall) signals in the East Asia, Australia, the Eastern Pacific, southern portions of South America (Central Canada, southern USA), the temperature (rainfall) anomalies in Central Asia, Canada (Indonesia, the western tropical Africa) could not be predicted correctly. The weak tripolar sea surface temperature conditions in the tropical Pacific since March 2008 resemble a so called La Nina Modoki condition. In the recent four weeks, the cold anomalies in the central tropical Pacific have slightly strengthened further; also, low level easterly wind anomalies are seen in the tropical western Pacific since November.
