>INTRODUCTION In the controversial paper “Advancing Decadal-Scale Climate Prediction in the North Atlantic Sector”, Keenlyside et al used the Atlantic SST dipole index as an indicator of Thermohaline Circulation/ Meridional Overturning Circulation (THC/MOC), as opposed to the Atlantic Multidecadal Oscillation … Continue reading →

>INTRODUCTION There are a good number of studies of the 1976 Pacific Climate Shift. Many of them discuss the processes that initiated the shift as modeled in GCMs; others illustrate the resulting effects on climate in the North Pacific and … Continue reading →

>The third version of the Extended Reconstructed Sea Surface Temperature (ERSST.v3) is available in ASCII format in a number of data sets segmented by latitude. The data spans the period of January 1880 to April 2008. It has not been … Continue reading →

>No. The Armagh Observatory in Northern Ireland has monitored and recorded the number of storms with gale winds since 1796, with a short period in the early 1800s (1825 to 1833) during which data is not available or incomplete. The … Continue reading →

> INTRODUCTION In a prior post I divided global SST anomaly data into quadrants.http://bobtisdale.blogspot.com/2008/09/sst-anomalies-by-global-quadrants.html In this post, I first lopped off the high latitudes to eliminate the Arctic and Southern Oceans. Then I divided the globe using longitudes to isolate … Continue reading →

>CORRECTION In the opening paragraph of this post, I make the following statement: “The newsworthy item this month is the change in the direction of the NINO3.4 SST anomaly data. It’s a minor drop, but it has dropped. IF, big … Continue reading →

>INTRODUCTION Every now and then I’ll find some phrase or comparison in a blog post or comment or a climate research paper that initiates a new search for a correlation or causal relationship between solar irradiance and ENSO. While I … Continue reading →

>INTRODUCTION The following discussion was contained in my recent post about the Tropical West Pacific.http://bobtisdale.blogspot.com/2008/10/tropical-sst-anomalies-revisited-west.html I felt it important enough to warrant a post of its own. I have not changed the numbering of the figures, which is why the … Continue reading →
