| As ENSO is buried, does the La Nina phoenix arise? |

Page 2 of 3 These reversals are being transposed around the Southern Hemisphere. The air, far less dense than the ocean, takes rather longer to erase the affects of the Southern Oscillation. This appears to be the cause for delay in southern African weather to recover from the ENSO effect. The translation from the one pattern to the other is already well advanced. But with a return to normal so late in our rain season, the weather has much catching up to do. Currently, across the eastern sub-continent, weather more in line with a pre-Christmas regular pattern is active. That part of the world expects the rainfall season to be declining during March and even more so in April. The rainy activity noted by the early to mid March NOAA report is definitely out of normal character. Now, does this mean that a micro-summer season will come, build and then fade across the central and western sub-continent? The current La Nina-type condition with SSTs is around 1oC below the mean for this time of year and appears to be extending its influence rapidly. Already, there is a positive, summer-style anticyclonic pattern returning. There are two anticyclonic cores plotted in the 40oS latitude. This is a considerable change for the pattern of development and movement prevailing across the past few months. |
