I had a career first this week - I was on the news! I talked about the extreme rain event in St. Louis in July 2022 and how my recent publication estimates that it is about twice as likely as we previously thought. YouTube link to the interview: www.youtube.com/watch?v=MZ7n...

A new twist to science communication: AI-generated articles trained on science press releases. One of these was written about my recently published study on extreme precipitation in the Central US. The training prompt must have been, um, interesting...

🌧️ Science Alert 🌧️ I am pleased to share newly published work that blends precipitation from both observations and climate models to more precisely assess an extreme precipitation event that took place in July 2022 and caused major flooding across St. Louis, MO and eastern Kentucky (1/6)

Year-end report for 2024 daily high temperature from the station at Boulder's NOAA lab: days warmer than the historical mean (1893-2023) outnumbered colder days by ~2.3 to 1

In the lead up to the #PalisadesFire and #EatonFire (using data from a nearby station at UCLA), Southern California experienced one of its wettest periods on record during Jan-Apr 2024 and has not had meaningful rainfall since 🤯 Mindblowingly favorable meteorological conditions for large wildfires

The last ClimateDataVisualizer example for AGU is the August 20, 2023 rainfall event in Death Valley NP from remnants of Hurricane Hilary. This event was the single highest recorded day since 1912 and accounted for an entire year's worth of 🌧️ in a single day

Today’s ClimateDataVisualizer example for AGU is annual rainfall for Western Maui in the years preceding 2023’s devastating wildfire. Some of the lowest annual rainfall totals since 1920 occurred in the last few years, drying out the region and priming it for a severe wildfire.

Today’s ClimateDataVisualizer example for AGU is the near-record 2023 cumulative rainfall year in Southern Vermont, which includes an extreme rainfall event on July 10-11. The lines are colored by year and show that as the climate warms, total annual rainfall tends to increase.

Today’s ClimateDataVizualizer example for AGU is the 2021 Pacific NW heat dome as shown in Portland, OR. NOAA ACIS observations show daily high temps on June 26-28, 2021 up to 9°F higher than any previous day since 1874. In fact, the Portland-wide avg from 4 stations topped out at 115°F on June 28!

Although I am attending AGU virtually this year with a newborn at home, I wanted to share a climate data web tool I have been working on over the past several months called Climate Data Visualizer. Give it a try at climate-data-viz.com! A quick 🧵(1/6)

For my first post on 🟦 I want to share a Python-based app I am making that visualizes the complete climate history of any place in the US. It's a work-in-progress, but I plan to make it a standalone website in the near future! The current app can be accessed here: sites.google.com/view/ajtclim...

This is an example of a data visualization for daily high temperature in St. Louis, Missouri
