Impact of a crosswind on a fly ball.John Farley/WAM

To explore this topic, I had a conversation with John Farley, the Chief Technology Officer for Weather Applied Metrics (see this link for an information video). The company quantifies weather impacts on baseball (and sports in general) using Computational Fluid Dynamics (CFD) modeling, standard trajectory physics, and other meteorological analysis. According to Farley, the company has a team of six: two PhDs – one is a retired meteorology professor, one is a CFD engineer, one master’s degree meteorologist, a college physics student, a CEO of a Silicon Valley Company, and a San Francisco Bay Area broadcast meteorologist. Farley reached out to me, and I was immediately fascinated. In my scholarly research, I study urban meteorological processes so was familiar with the use of Computational Fluid Dynamics modeling (good tutorial at this link) to simulate flow around buildings or to track tracer flows for hazardous materials. There are many applications of CFDs, but I really never thought one would be at a baseball stadium. Weather Applied Metrics installed its Beta site at the Columbia Fireflies stadium. The Fireflies are the Single A Affiliate of the New York Mets in Columbia, South Carolina. Farley told me,

You may recall that Tim Tebow hit a home run in his first at bat with the Fireflies. That day the weather helped carry that ball by roughly 15-18 feet and it cleared the fence by a few feet. So without the weather, it would probably have been a warning track out. Last June we installed our technology in an MLB park and we are now in the final stages of completing an agreement with them for the 2019 season.

I was so fascinated by what this company was up to that I conducted a Q & A with Farley. Our conversation is summarized below.

Dr. Marshall Shepherd: How does weather affect baseball trajectory?

John Farley: If the wind is blowing hard, that’s the most significant impact. A headwind, combined with a down draft, can shorten a fly ball hit to the wall by as much as 60 feet. A tail wind, combined with an updraft can lengthen it by as much as 45 feet. Since baseballs absorb moisture from the air (they are hygroscopic), the difference in distance between very dry air and very wet air is roughly 50 feet. That’s because a wet ball is slightly heavier and spongier, so it doesn’t come off the bat as fast. On a hotter day the air is less dense and so a ball can travel as much as 30 feet farther, compared to a cold day. Air pressure affects density directly. So balls hit at high altitude travel considerably farther. In the graphic above, our analysis is an example of a cross wind over a major league stadium. With the resulting downdraft and headwind in right field, the ball’s flight is shortened by roughly 30 feet.

Dr. Marshall Shepherd: Can it significantly impact outcomes and is there a way of determining?

John Farley: Yes. Our real-time display at the Fireflies Stadium in Columbia, SC shows how much the weather is impacting the distance of an average fly ball hit to the outfield fence (averaging 375 feet). Blue numbers are feet added. Red numbers are feet subtracted. Here are a few examples from games. The arrow at home plate shows the prevailing wind. In this smaller stadium, the prevailing wind is very representative of the winds over the flight of the ball.

Dr. Marshall Shepherd:  How are you using Computation Fluid Dynamics (CFD) Modeling to study baseball?

John Farley: CFD is necessary because the wind flow inside stadiums is very complex and often very different from what the flags show on top of the stadium. Additionally, what’s been missing from all of the baseball trajectory analysis that we’ve seen is vertical wind (as meteorologists that’s all we think about!). And there is a lot of vertical wind inside stadiums, which has a significant impact on the flight of the ball over its entire trajectory. Prevailing winds (see graphic below) blowing over a stadium in one direction, but the winds at field level doing the exact opposite, and there’s a lot going on in between. We model the wind field down to each square foot over the entire area where a ball could fly. Then we use those winds for our 3D-Trajectory model with increments of 0.001 seconds.

Dr. Marshall Shepherd:  Why are you doing this?

John Farley: We are weather and sports geeks and we are very curious! Why else would we do this?;-) As meteorologists, we’ve always know that weather has a huge impact on sports. Now we can tell you exactly what’s going on with each ball.

Farley and colleagues may be on to something, but only time will tell. He provided me with a summary of how Weather Applied Metrics (WAM) illustrates the impact of weather on baseball. Data was collected for all home games for the Columbia South Carolina Fireflies for the 2016 Season. The bulk game statistics show some pretty compelling impacts on runs per game, earned runs per game, home runs per game, and hits per game.

To explore this subject, I had a discussion with John Farley, the Chief Innovation Officer for Weather Condition Applied Metrics (see this link for a details video) The business measures weather condition effect on baseball (and sports in basic) utilizing Computational Fluid Characteristics (CFD) modeling, basic trajectory physics, and other meteorological analysis. According to Farley, the business has a group of 6: 2 PhDs – one is a retired meteorology teacher, one is a CFD engineer, one master’s degree meteorologist, a college physics trainee, a CEO of a Silicon Valley Business, and a San Francisco Bay Location broadcast meteorologist. Farley connected to me, and I was right away amazed. In my academic research study, I study city meteorological procedures so recognized with making use of Computational Fluid Characteristics modeling ( great tutorial at this link) to imitate circulation around structures or to track tracer circulations for dangerous products. There are lots of applications of CFDs, however I actually never ever believed one would be at a baseball arena. Weather condition Applied Metrics installed its Beta website at the Columbia Fireflies arena. The Fireflies are the Single A Affiliate of the New York City Mets in Columbia, South Carolina. Farley informed me,

You might remember that Tim Tebow struck a crowning achievement in his very first at bat with the Fireflies. That day the weather condition assisted bring that ball by approximately 15-18 feet and it cleared the fence by a couple of feet. So without the weather condition, it would most likely have actually been a caution track out. Last June we installed our innovation in an MLB park and we are now in the lasts of finishing a contract with them for the 2019 season.

I was so amazed by what this business depended on that I performed a Q & A with Farley. Our discussion is summed up listed below.

Dr. Marshall Shepherd: How does weather condition impact baseball trajectory?

John Farley: If the wind is blowing hard, that’s the most considerable effect. A headwind, integrated with a down draft, can reduce a fly ball struck to the wall by as much as 60 feet. A tail wind, integrated with an updraft can extend it by as much as 45 feet. Because baseballs soak up wetness from the air (they are hygroscopic), the distinction in range in between really dry air and really damp air is approximately 50 feet. That’s since a damp ball is a little much heavier and spongier, so it does not come off the bat as quick. On a hotter day the air is less thick therefore a ball can take a trip as much as 30 feet further, compared to a cold day. Atmospheric pressure impacts density straight. So balls strike at high elevation travel significantly further. In the graphic above, our analysis is an example of a cross wind over a big league arena. With the resulting downdraft and headwind in ideal field, the ball’s flight is reduced by approximately 30 feet.

(********************* )Dr. Marshall Shepherd: Can it substantially effect results and exists a method of figuring out?

John Farley: Yes. Our real-time display screen at the Fireflies Arena in Columbia, SC demonstrates how much the weather condition is affecting the range of a typical fly ball struck to the outfield fence (averaging 375 feet). Blue numbers are feet included. Red numbers are feet deducted. Here are a couple of examples from video games. The arrow in the house plate reveals the dominating wind. In this smaller sized arena, the dominating wind is really representative of the winds over the flight of the ball.
