I've recently launched a newsletter called Weather and Vines, which covers weather, climate, and wine on an irregular schedule. I'm still working out the quirks, but you can sign up at weatherandvines.com. The newsletter is targeted towards anyone who is interest in weather and wine, no technical knowledge required.

Kyle MacRitchie

Meteorologist and Data Scientist


I specialize in creating statistical and dynamical/statistical hybrid models that objectively predict weather and climate conditions more than a week in the future. I believe that the future of weather forecasting revolves around statistical forecasts that harness the physical laws of the atmosphere.

Work Experience

Applied Scientist

Descartes Labs | 2021 - Present


Climate Prediction Center (NWS) | 2018 - 2021

I am a hybrid operational meteorologist and researcher focused on integrating the latest science with the National Weather Service’s forecasting process.

  • Operational model and forecast verification
  • Developed neural network and linear models to predict ENSO and U.S. temperature and precipitation at weeks 3-4 leads
  • Operational forecaster: MJO and tropical hazards, U.S. hazards, weeks 3-4 forecasts
  • Python w/ ArcPy scripting to support ArcMap use in our operational products.

Atmospheric Scientist

Innovim, LLC | 2016 - 2018

I was a contractor for the Climate Prediction Center charged with creating operational tools for week 3-4 forecasts.

  • Dynamical model calibration for tools that support weeks 3-4 forecasts
  • Provided guidance and assistance on MJO and tropical hazards products

Research Meteorologist

RiskPulse (formerly EarthRisk) | 2013 - 2016

I was in a consulting position to help RiskPulse improve predictions for their customers.

  • Worked to improve predictions using intraseasonal and interannual atmospheric and oceanic variability
  • Spearheaded a number of projects to assess model skill and bias under different atmospheric regimes; created a website with this information for clients
  • Worked with team to refine our predictability ideas and incorporate them into other projects as appropriate

Data Support Scientist

ADNET Systems, Inc. | 2015 - 2016

I was a contractor working in the GES-DISC data center at NASA Goddard Space Flight Center.

  • Managed a transition of metadata for > 1,000 products to a new database
  • Created multiple Python programs to interface with EarthData’s RESTful API for myself and others to use to aid the metadata transition.


College at Oneonta/SUNY | 2013 - 2015

I was a full-time lecturer for four semesters while finishing my dissertation.

  • Created and taught courses to undergraduates: Introduction to Meteorology, Tropical Meteorology, Physical Meteorology (Thermodynamics), Environmental Issues, and Senior Seminar
