SW Climate Outlook Monsoon Tracker - Sept 2017

Friday, September 22, 2017

The North American monsoon was quiet for much of the Southwest through early July, but mid-July through early August saw an impressive run of storms. July was particularly active in southeast Arizona, where numerous locations approached or set single-month records for precipitation. Since early August, however, Arizona has experienced a widespread shutdown of monsoon activity, while New Mexico has seen more regular precipitation. (read more)


SW Climate Outlook - ENSO Tracker - Sept 2017

Friday, September 22, 2017

Oceanic and atmospheric indicators remain within the range of neutral but have shifted more towards La Niña conditions in the past month (Figs. 1-2). Seasonal outlooks and forecasts reflect these changes, and most now see La Niña conditions as the more likely outcome for fall 2017, with ENSO-neutral conditions mostly still favored for winter.

SW Climate Outlook Sept 2017 - Climate Summary

Thursday, September 21, 2017

Precipitation and Temperature: August precipitation ranged from much-below average to average across most of Arizona and New Mexico, except in eastern New Mexico where above-average to record-wettest conditions prevailed (Fig. 1a). August temperatures were average to much-above average in Arizona and most of New Mexico, with only the northeastern corner of New Mexico recording below-average temperatures (Fig. 1b). Temperatures during the June-July-August period have been mostly much-above average in Arizona and western New Mexico, and average to above average in eastern New Mexico (Fig. 2a). Year-to-date temperatures are persistently warmer than average, with much-above average and record-warmest conditions across nearly all of Arizona and New Mexico (Fig. 2b). (read more)

Beginning to Understand Climate Change in the Kaipara Catchment

Thursday, September 14, 2017

I’ve tagged along on environmental monitoring patrols, ridden in logging trucks with forestry workers, played cow wrangler on a dairy farm, photographed coastal erosion from the back of a four wheel drive that smelled of turkeys, and attended a conference on the wellbeing of eels. I’ve had conversations on boats and beaches, in fields and farmhouses, by lakes, in rivers, cars and marae (meeting houses). This is what happens when an anthropologist is on the case. (read more)

Climate and Water Resources of the Chuska Mountains

Monday, September 11, 2017

In the fall of 2015, I began working with the Navajo Nation Department of Water Resources, Water Management Branch, to address water resource management questions they had for the Chuska Mountains. These mountains are the only native headwaters on the Navajo Nation, where water scarcity impacts Navajo tradition, culture and livelihood. Since our initial discussions, Water Management Branch staff and I have collaboratively developed guiding research questions about past changes in water and climate. (read more)


Rainlog Climate Summary – August 2017

Tuesday, September 5, 2017

After an exceptionally wet July for many areas across Arizona, monsoon storm activity slowed down to a crawl leading to unusually dry conditions over the past month. August is typically the wettest month during the summer monsoon season in Arizona and the lack of thunderstorm activity stands out against the frequent and heavy activity that characterized much of the month of July.

SW Climate Outlook - Monsoon Case Study - Pima ALERT Network

Monday, August 21, 2017

Comparison of the current totals at regional weather stations to normal precipitation-to-date and average seasonal totals gives a better sense of how locations across the region are faring in the monsoon (Fig. 1). Most of the stations in Fig. 1 recorded average to above-average precipitation to date, and a few (El Paso and Tucson) exceeded the monsoon seasonal average (June 15 – Sept 30). 

Looking at the Pima County ALERT network sensors (Fig. 3) reveals just how variable the monsoon can be within a region, as well as the fact that daily & cumulative single-station values may not reflect the range of precipitation values observed in the monsoon. read more
