Notes From the Field: Preparing for Climate Change Along the US-Mexico Border

Monday, October 27, 2014

On September 10-11, 25 scientists and natural resource managers met at the offices of the International Boundary and Water Commission (IBWC), in El Paso, Texas.  Their goal was to use strategic scenario planning techniques to gain insight into environmental and natural resource planning under highly uncertain conditions. Participants included climatologists, meteorologists, geologists, hydrologists, ecologists, biologists, and environmental economists, representing a range of U.S. and Mexican federal agencies, state agencies, universities, and non-governmental organizations.

Notes from an Applied Climatologist: Monsoon End Q&A

How Do We Know When the Monsoon is Over?

Across the southwest United States, the start of the summer monsoon season is pretty easy to recognize once you have experienced it firsthand a few times. Typically, one week it's hot and dry, and the next week, it's hot and sticky, but hopefully raining. (read more)

Notes from an Applied Climatologist - July 2014 Rainlog Climate Summary

Tuesday, August 5, 2014

July started off with a bang with moisture and thunderstorm activity moving into Arizona over the 4th of July weekend. This start date for monsoon thunderstorm activity was very close to the climatological start date of July 3rd, as determined by the old dewpoint definition (three consecutive days with average dewpoints >= 54F) in Tucson. The ‘monsoon ridge’ of high pressure was in an ideal position over the first two weeks of July to guide abundant subtropical moisture into the state, providing fuel for almost daily thunderstorm activity across parts of southeastern Arizona and the high country along the Mogollon Rim.

Notes From the Field: Thinking Outside the Box with Great Basin Natural Resource Managers

Tuesday, July 15, 2014

On June 25-27, 2014, a team of researchers from CLIMAS and the California-Nevada Applications Program (CNAP) convened a workshop at the Desert Research Institute in Reno, NV.  The goal?  We wanted to address the complex and uncertain future of Great Basin land management in the Central Great Basin (California and Nevada), and to provide state and federal agency partners with streamlined and purposeful means of incorporating climate change information into land management practice.

Notes from an Applied Climatologist - June 2014 Rainlog Climate Summary

Thursday, July 10, 2014

June was a hot and dry month across Arizona with little in the way of precipitation and lots in the way of wind and extreme fire weather. This isn’t all that unusual for June in Arizona, but temperatures were exceptionally warm and passing weather systems brought unwelcome wind which periodically enhanced fire danger to extreme levels. The weather pattern throughout the month was a battle between the strengthening sub-tropical high to our south and late season spring storm pushing through the Southwest from the north.  (read more)

Notes from the Field: Dendrochronology, Wildfire, and Iron Maiden

Tuesday, June 24, 2014

Just how old are the forests in the Chuska Mountains in the northeastern part of the Navajo Nation? How might those forests fare in a climate that will be warmer and probably drier than anything they've ever experienced?

In early June I had the chance to tromp around in the woods with a group of experts working to answer these questions. Our intrepid leader was UA Laboratory of Tree Ring Research PhD student Chris Guiterman who—I now know—is a man with a plan. The plan goes something like this...(read more)
