Talk at Charles Darwin Research Station

Photo: I gave the talk in Spanish - but wasn't sure whether English was also OK - it was.

Photo: we ran a pilot balloon network from 1997-2006 at many of these sites (not all at same time)
Photo: basics of pilot balloons - for wind profile determination by tracking with theodolite
Photo: this is a theodolite - ancient US model from the 40's - but they work.  Skilled observer is key.  This is at San Fernando de Apure, Venezuela.
Photo: our first trip to Galapagos was on this Ecuadorean Navy Research ship - El Orion.  They invited us to make met observations.  And since I'd never been on a research cruise I (and another colleague) was happy to participate.
Photo: these are sea-surface temperature charts - self explanatory
Photo: a radiosonde profile (temperature in red, relative humidity in blue) made from the Orion near Isabela.  Note strong temperature inversion with base near 900 m.
Photo: meridional wind profiles based on pilot balloons for different months.  strong southerly flow confined to lowest 1 km.
Photo: another view of same - but June-Sept 2005.
Photo: highlighting "stable climate"
Photo: monthly wind profiles during the big el niño event 1997-98 from the pilot balloon data.  These sounding were made twice-daily, most stations were once-daily.

Photo: this sequence shows evolution of the equatorial cold tongue - cooler SST's along the equator in the eastern Pacific.
Photo: note strong coastal upwelling - much colder temperatures along coast
