Solar Cycles and the Equatorial Trough: An Alternate Conceptual Model

by Michael Wallace, Hydrologist I have offered to write this guest essay to reflect recent talks I’ve presented to water resource professionals on hydroclimatology and Solar cycles. As an academic and hydrologic forecaster, I have followed an energy centric, reproducible data path to quantify correlations between solar cycles and atmospheric moisture patterns. I have anchored…

Study finds: Middle atmosphere temperature in sync with the ocean PDO

Relationship between decadal variations in temperatures in the Pacific and the tropopause identified From the HELMHOLTZ CENTRE FOR OCEAN RESEARCH KIEL (GEOMAR) Water plays a major role for our planet not only in its liquid form at the surface. In the atmosphere too, it considerably affects our lives as well as weather and climate. Clouds and…

Has the PDO flipped?

Guest post by David Middleton Cyclical changes in the Pacific Ocean have thrown earth’s surface into what may be an unprecedented warming spurt, following a global warming slowdown that lasted about 15 years. While El Niño is being blamed for an outbreak of floods, storms and unseasonable temperatures across the planet, a much slower-moving cycle…
