Climas - Southwest Climate Podcast

In the November edition of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido look back to monsoon 2021 to do a recap of the seasonal totals.  They are joined by Paul Iniguez, the Science and Operations Officer for the National Weather Service office in Phoenix, to take a closer look at the 2021 monsoon, how it stacked up around the region, and to hear a bit more about how the NWS offices work across the monsoon. This is a single focus episode - see the Oct 2021 episode for the normal monthly roundup and recap. Watch this space: https://www.weather.gov/psr/eventsummaries for the 2021 monsoon recap from NWS Phoenix, as well as some detailed storm event reports from across the season (and year).

In the October 2021 edition of the Southwest Climate Podcast, Mike Crimmins and Zack Guido reconvene after a long pause to revisit recent conditions in September and October, dive into what ENSO and La Niña might have in store for the Southwest, and what the Double Dip is and why it's more likely in back to back La Niñas.  For monsoon fantasy players, they recap the monsoon game and how the leaderboard shook up in the final day in the first segment.  Production note: We recorded two podcasts this week, the standard monthly recap (this podcast) and a monsoon recap extravaganza with Paul Iniguez of the NWS office up in Phoenix.  Look for that monsoon recap podcast in a few days (also in this feed) and keep an eye on the NWS pages for their in-depth monsoon recaps.

In the September Edition of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido sit down to revisit last month's discussion of a generational monsoon. They check in around the region to see how various locations are faring and discuss the interesting patterns they've seen in monsoon activity so far. They put the totals to date into climatological context and rankings, to see who is experiencing a generational monsoon, vs. areas that are "just" above average (or who are lagging behind).  They wrap with a discussion of "Is the Monsoon Over" - and talk about the reasons why you may/may not think so, and what the transition season means for the last few weeks of the monsoon (and the final seasonal rankings).

In the August 2021 edition of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido sit down to discuss the "monsoon that comes to you" (i.e. it's just about everywhere, and it just keeps coming!).  They discuss the (record) July for some areas, as well as the well above average conditions around much of the region. They also deconstruct the elements that are feeding into this persistent monsoon rainfall and take a deep dive into a few of the events that have contributed to impressive totals.  They wrap up with a discussion of outlooks for the rest of the season, whether any stations might hit record monsoon totals (Tucson is definitely in the running), and what this has meant for the monsoon fantasy game (suffice to say, the guesses for July did not anticipate the record wet conditions).

In the (mid/late) July edition of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido are back at it, given all that happened with the monsoon since early July.  First, they dive into monsoon conditions around the region, to put them into climatological perspective, while discussing some of the defining characteristics of the monsoon. Next they grapple with the question: Is this shaping up to be an all-timer for July, given all the rain that's already fallen (and what is in the forecast for the rest of July)?  The answer is complicated (tune in to hear where they land on this).  Finally, they look a bit at the forecasts and outlooks for the upcoming weeks and months and remind us about the monsoon fantasy game that we are running this monsoon. A reminder from the Southwest Monsoon Fantasy Forecasts game: We pose this question to you: will August be wet, dry, or in between at stations around the Southwest? So far, the monsoon has been wet in many places, with an active monsoon pattern over

In the June/early-July edition of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido sit down to discuss weather and climate in the Southwest.  They start with June heatwaves, and where these sit in comparison to climatology/normal for the Southwest, and how they differ from the record heat waves seen in the Pacific Northwest.  They transition to a discussion of the early(ish) onset of the monsoon this year, and whether this bodes well for a better monsoon than last year (frankly, this is a low bar to clear).  Finally, they recap their own (forecast) guesses for July and run through the Southwest Monsoon Fantasy Forecast game we are trying out this year. https://monsoonfantasy.arizona.edu/ We plan to do another podcast in mid/late July to see where things stand with the monsoon, but so far, so good (or at least better than last year).

In the May 2021 edition of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido sit down to discuss a range of issues related to that most pressing question this time of year - "What's the Monsoon Forecast?!".  They run through the last month of weather, what we might expect from June given historical patterns and extremes, and how much faith we can put in forecasts this time of year (hint, it's tough to make a good monsoon forecast). The podcast wraps with a reminder about the Southwest Monsoon Fantasy Forecast game. We piloted the game last year, and this year there's a new and improved interface and some fun prizes.  Stay tuned to the end of the podcast (or watch this space) for details on the game (how to play, prizes, etc.). 

In the April 2021 episode of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido jump into winter weather and assessments of (drought) conditions.  First, they look back at winter so far and see how it stacks up to recent historical totals. Next, they take a closer look at the relationship between summer and winter precipitation, and the various phase combinations (wet/dry, dry/wet, wet/wet, dry/dry). They turn to some paleoclimate expertise to help them think about these patterns, as well as how drought has been defined (seasonal drought, megadrought, etc.), and how these terms get used in science communication and the media.

In the Mar 2021 edition of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido sit down to discuss the winter in the Southwest, and whether it lived up to expectations for a La Niña winter. They also go over streamflow, snowpack, and start a deeper dive into reservoirs, based on a listener question from last month (send in your questions if you have them!). They dabble a bit in the seasonal forecasts and talk about some of the key things they will be watching over the next 3-4 months, namely how fire season evolves, and when we can (reasonably) start looking ahead towards monsoon onset. They wrap up with a brief preview of monsoon-game 2.0, and hint at what we have planned.

In the February 2021 episode of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido jump back into discussing winter conditions in the Southwest. This includes what happened so far in 2021 with a few runs of storms that affected parts of Arizona and New Mexico. This also includes the role that La Niña may be playing this winter (snowpack, streamflow forecasts, rain/snow events, etc.), and how this compares to previous winters and La Niña events. They also discuss what we might expect for the rest of the "wet" winter season (really, Feb-Mar) in the arid Southwest. 

In the Dec 2020 edition of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido sit down to discuss drought, La Nina, and what to expect (or at least hope for) in 2021. First, they recap the event that swept through on Dec 9-11, to talk through how different locations in the region fared in terms of precip.  Next, they transition into the drought situation, which is currently looking pretty dire for the region - and discuss 'just how much worse can it get' - given much of the region is at Exceptional Drought (D4, the highest category on the US Drought Monitor), looking to some past events for comparison. They wrap things up with some 2021 predictions - things they think could (or hope might) happen in 2021.

In the November episode of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido sit down to discuss weather and climate in the Southwest, including what we might expect over the next few months.  They discuss La Niña and what this might mean for the Southwest, including implications of La Niña following a much drier than average monsoon and what the historical record says about just how unprecedented this pattern might be (dry monsoon, dry winter). Finally, they take a closer look at fire, and how the season has progressed in the Southwest, given the lack of rain, and what we might watch for going into next year's fire season.

In the October 2020 edition of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido open up with something fun - with a quick rundown of the Monsoon Game 2020, congratulating Mike (for his CLIMAS podcast team victory, with 33 points) and Aaryn O with his overall victory (56 points). Next, they look back on the monsoon, and try to make sense of some of the reasons that might have contributed to the widespread below average (or even record driest) conditions in the Southwest. They take a closer look at some of the mechanisms that might be in play and review a few papers that address the role of climate change in a changing monsoon. Finally, they look forward (begrudgingly) at winter 2020-2021, which is lining up to be either a moderate or strong La Niña, and the discuss the implications of forecasts for a drier than average winter stacking on top of a very dry monsoon.

In the September 2020 edition of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido reflect on this year's monsoon.  The monsoon is not over, but at this point it is clear it will come in on the dry side of things. They discuss some of the reasons why, and how this below average monsoon compares across the region and to other years. Zack also recounts some of our Slack/text conversations about the monsoon and maps them onto the 5 stages of grief framework. They also discuss tropical storm activity in the eastern Pacific and talk through the monsoon game for August. There is not much on the horizon for the rest of September, but we have been surprised before, so here's hoping!

In the August 2020 edition of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido sit down to discuss "what is going on with monsoon 2020?!" This includes a review of different locations around the U.S. Southwest, where some locales are just barely hitting long-term averages, while others are running at record or near-record driest levels (so far). They also cover some of the factors driving these patterns, what we might expect in the 2nd half of the monsoon, and where this ranks in terms of the regional precipitation records (and unmet expectations). They wrap with a discussion of the monsoon game, which is fun despite the relatively dry conditions - especially for those that leaned on the dry side of their guesses in Arizona. The results for July are posted below, and congrats to Doug D on topping the July leaderboard. We also finally have some podcast gear (shirts and mugs).  You can order them at https://teespring.com/stores/the-southwest-climate-podcast. We set the prices at wholesale co

In the July 2020 edition of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido update their discussion of the 2020 wildfire season, which is turning out to be quite active for Arizona (while New Mexico is relatively quiet). Next, they move on to monsoon 2020, focusing on what the outlooks and forecasts had to say about this year, how this slow start compares to previous years, and asking the question ‘does a late start matter?’ for the overall seasonal totals (hint: it’s complicated). They also include a discussion of “key numbers” for the monsoon and a discussion of some recent literature about the role of widespread precipitation events and regional monsoon precipitation totals. They are joined at the end by Ben McMahan to talk a bit about the monsoon guessing game - where they discuss the guesses they received for July and look forward to seeing even more people play for August and September - Details Below: Monsoon Game Details: Ben, Zack, and Mike developed a monsoon game that anyone ca

In the June 2020 edition of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido sit down to talk about the last month of weather (including what Zack has coined the "TooSoon"), the current conditions (including the wildfire situation) and look forward to the monsoon. The monsoon may have officially started on June 15th, but they discuss why we are probably at least a few weeks away from seeing much in the way of rain. Also, we developed a 'play at home' game for guessing monthly monsoon totals, and we're excited to open this up to the general public. You can enter the game (and fill out a short survey about the podcast if you want at https://uarizona.co1.qualtrics.com/jfe/form/SV_eA1GfWVmsatWDLD The link explains the game, and Zack also lays out the rules and points on the podcast.  The game will be for the months of July, August, and September, so you have till June 30th to get your July guesses in.  We'll run another entry for August in July, and so on. Happy Monsoon!

In the May 2020 edition of the Southwest Climate Podcast, Mike Crimmins and Zack Guido sit down to discuss a bit more about the winter that was, summer heat (and the current spring/May heat), the upcoming monsoon, and some of the seasonal hazards we see in the Southwest this time of year (heat, wildfire, air quality). They also look to the monsoon and summer seasonal outlooks and the factors affecting monsoon timing and intensity, offering some insight into what we can (or can't) say about monsoon forecasts (before each giving one of their own). They conclude with a bit of ENSO discussion, given the possible La Nina on the horizon.

In the Mar 2020 edition of the Southwest Climate Podcast, Mike Crimmins and Zack Guido sit down to discuss winter conditions across the Southwest, the state of snowpack and snow water equivalent around the west, and water supply and streamflow forecasts as we look to spring and summer.   Discussed in this Episode: Colorado River flow dwindles as warming-driven loss of reflective snow energizes evaporation - P.C.D.
