La-Nina

The transition from the relatively stable to gradually cooling Holocene climate state to climate conditions above 2 degrees C involve increase in the amplitude of the ENSO cycle, a rise in the frequency of the El-Nino and a decrease in the frequency of the La-Nina phases.

After the Powerful El-Nino of 1998, there was an extended La-Nina:

I understand that the recent La-Nina have not brought rain as expected but surely that expection was based on previous observations.

Will post soon on my website the most compelling results of the spring of 2009, suffices to say, the warming trend continues, despite La-Nina bumps.

I translate this as effects of La-Nina starting from a higher energy atmosphere, corresponding to overall higher temperatures throughout the atmosphere at the beginning and the end of a LaNina (not necessarily measured fully measured by conventional means due to lack of data resolution).
