Track Record

Company Highlights Date Forecasting Track Record



From 1989-1991, StatWeather founder Ria Persad discovers new methods of solving Partial Differential Equations, and MIT awards her a supercomputing fellowship at Lawrence Livermore National Lab using a new generation of CRAY technology applied to climate modeling. These cutting-edge models would later form the basis of the CCM climate models now in use by the international community of the IPCC and would foreshadow the founding of StatWeather.

June 1991  

Winter 1991


Microsoft Excel is initiated as the hot new analysis tool on Wall Street. Persad is employed to program predictive spreadsheets for stock prices at Lehman Brothers and the American Stock Exchange while a student at Princeton University.

Dec 1991  

Spring 1993


Parallel Computing in Weather
CRAY Research offers its first massively parallel processing system, and Persad returns to Lawrence Livermore National Lab to engage in climate modeling using advances in parallel and distributed computing, which would later provide the paradigm for StatWeather.



Scientific Achievement Award
Persad receives citations from U.S. Secretary of Energy Hazel O'Leary and Senator Edward Kennedy for Scientific Achievement.




Warm Trend Detection
Climate models at Lawrence Livermore National Lab predict nearly 20 years in advance a warming trend culminating in the year 2010 being the warmest year on record for global temperatures and 2012 being the warmest year on record for the Continental U.S. The model verifies 20 years later with piercing accuracy and far-reaching implications.



Research Published at Cambridge
Professors at Cambridge University publish seminal research on dynamical systems and chaos theory, providing a new, breakthrough framework for Persad's weather model development. Cambridge Professor G. I. Barenblatt would later serve on the advisory committee of StatWeather.

1994 to 1995  



Utilization in Aerospace & Energy
Persad develops for NASA an analytical model predicting chaos in non-Hamiltonian systems and later builds statistical models for long-range weather prediction at Bell Geospace, Enron, and Duke Energy.

1996 to Now



Unprecedented Accuracy
FACT: Since 1997, none of Persad's U.S. season-ahead forecasts have ever gone "bust". Eighteen years later, the legacy of reliably accurate seasonal forecasting continues to this day with StatWeather.



Persad Develops ClimeCast

Persad develops ClimeCastTM,the first purely statistical, post 5-day weather model on the market. Broadcast and government scientists pilot ClimeCast.

2001 to 2006


ClimeCast Outperforms Existing Models

ClimeCast's accuracy consistently out-performs government weather models 6-15 days in advance and the Pentagon explores its utilization in defense applications.



Artificial Intelligence
Persad prototypes a second-generation model using artificial intelligence, at that time a little-known technology among the weather forecasting community. Persad becomes a consultant for Goldman Sachs.

2006 to 2009

Jan 2009

Funding StatWeather
Using StatWeather algorithms, Persad invests in commodities using her own savings. Through a series of well-timed transactions, money is raised to bootstrap StatWeather until it becomes a profitable company 18 months after the first product release. "If I can multiply my money using these algorithms, others will be able to profit as well", says Persad.



Bayesian Breakthrough

A bleeding-edge third-generation model is created using Bayesian neural networks that renders a daily forecast up to 90 days in advance and a weekly forecast up to 1 year in advance.

2009 to 2011



Accuracy Validation

Back-testing is performed to validate forecast accuracy and marketability, and StatWeather's 16-90 day ahead model consistently out-performs 10-15 day ahead government forecasts for a random sample of 10 U.S. cities.



Industry Acknowledges Model Accuracy

Risk.net and Waters Technology's "Trading on Mother Nature" later document StatWeather's forecasting success for Winter 2011-2012. StatWeather's full product suite is showcased at the Energy Risk Summit in Houston, TX, and is extremely well received among risk managers.

Benchmarking StatWeather

Thomson Reuters' Global Head of Weather, Stephen Mitchell, benchmarks StatWeather's forecasts to ascertain its 3rd party accuracy. His conclusion: "I have not seen any weather company forecast 90 days ahead as consistently accurate as StatWeather. This has been a terrific winter to embark such a study given the many extreme weather events in the US. Describing this accuracy to my colleagues who trade commodities is like trying to convince someone you saw Bigfoot! The forecast validation statistics are practically unfathomable and are immediately met with disbelief. If I had not seen it for myself (operationally), I too would be in disbelief."

Midwest Prediction
Comes to Pass

Energy Manager Today publishes StatWeather's early Winter outlook: "Midwest energy managers should prepare for a stormy winter. Chicago, Ohio, Detroit will be most susceptible to stormy, cold, volatile weather, during October continuing to run cool into December, with January being the height of storminess." This prediction comes to pass months later, exactly as told.

StatWeather Surprises in Forecasting Community
Reuters reports on old-school meteorology vs. StatWeather's data-driven "quant" approach, saying, "NOAA had predicted this past winter was going to be warmer than normal. Instead, it was unusually cold - just as StatWeather predicted. StatWeather nailed calls on a cold snap in late 2013 and a string of frigid temperatures through March, surprising some in the forecasting community."
