Longer-Term Weather and Environmental Forecasts Will Provide Enormous Benefit with More Research and Sustained Investment, New Report Says
Source: The National Academies of Sciences, Engineering, and Medicine

Weather and environmental forecasts made several weeks to months in advance can someday be as widely used and essential as current predictions of tomorrow's weather are, but first more research and sustained investment are needed, says a new report from the National Academies of Sciences, Engineering, and Medicine.  COAPS director Dr. Eric Chassignet is a member of the committee that conducted the study and wrote the report. The committee developed a research agenda, outlining strategies to address the scientific and capability gaps that currently limit the accuracy and usefulness of long-term weather and ocean predictions.

Extending short-term forecasts to predict Earth system conditions -- conditions in the atmosphere, ocean, or land surface -- two weeks to 12 months into the future will help decision makers, such as local officials, farmers, military officers, or water resource managers, plan ahead and save lives, protect property, and increase economic vitality.  For example, naval and commercial shipping routes could be better planned to avoid hazards or take advantage of favorable conditions predicted for the weeks ahead.

The report outlines a 10-year agenda with research strategies to make seasonal and subseasonal forecasts more accurate and relevant. The report notes these research strategies will all require advances in the U.S. computational infrastructure to support subseasonal to seasonal forecasting and a national plan and investment strategy for the future.  The sheer volume of observational data, data assimilation steps, and model output involved in this forecasting challenges the limits of current cyber-infrastructure.  This growing subseasonal to seasonal field also needs a workforce able to cross traditional disciplinary boundaries within the Earth sciences, between computing and physical science fields, and to bridge the divide between researchers and decision makers. Read the four-page report brief.

SAMOS program helps improve weather predictions
Source: NOAA Climate Program Office (CPO)

Every day, ships, buoys, and coastal platforms take millions of surface temperature, pressure, humidity, and wind measurements from across the ocean.  Although these measurements help meteorologists predict the weather each day, they also play a key role in calibrating measurements from satellites orbiting the Earth.

Traditionally, marine weather measurements from ships are only taken once an hour.  This hourly sampling proved to be inadequate to calibrate satellite sensors--particularly those measuring winds over the ocean because the winds can change in a matter of minutes at any given location. To solve this problem, in 2003, a group of scientists designed a program to collect marine weather observations once a minute from oceanographic research vessels. Because satellites take many more readings than ships or other observation platforms, increasing the number of measurements on ships allowed scientists to better match ship and satellite observations in space and time.  This helped improve the methods used by satellites to measure surface weather conditions. These calibrated satellite data are, in turn, used by the computer models to improve daily weather forecasts.   

This program is known as the Shipboard Automated Meteorological and Oceanographic System (SAMOS) and it is led by the Center for Ocean-Atmospheric Prediction Studies at the Florida State University (FSU).  Read the full article.  
Activities & Achievements 
DOMS website launched
COAPS recently launched a website for the Distributed Oceanographic Match-up Service (DOMS), a web-accessible service tool that will reconcile satellite and in situ datasets in support of NASA's Earth Science mission. When complete, DOMS will provide a mechanism for users to input a series of geospatial references for satellite observations (e.g., location, date, and time) and receive the in-situ observations that are "matched" to the satellite data within selectable time and space tolerances of the satellite observations. The inverse of inputting in situ geospatial data (e.g., positions of moorings, floats, or ships) and returning corresponding satellite observations will also be supported. The DOMS prototype includes several characteristic in situ and satellite observation datasets. For the in situ data, the focus will be surface marine observations from the International Comprehensive Ocean-Atmosphere Data Set (ICOADS), the Shipboard Automated Meteorological and Oceanographic System Initiative (SAMOS), and the Salinity Processes in the Upper Ocean Regional Study (SPURS). Satellite products will include JPL QuikSCAT winds, the Aquarius orbital/swath dataset, and the high-resolution gridded MUR-SST product. Importantly, although DOMS will be established with these selected datasets, it will be readily extendable to other in situ and satellite collections, which could support additional science disciplines.  The DOMS development team includes partners from FSU-COAPS, the National Center for Atmospheric Research, and NASA's Jet Propulsion Laboratory.    
COAPS scientists to develop a quasi-real-time weather/climate prediction system for Korean research institute  
Drs. Dong-wook (DW) Shin and Steven Cocke have been enlisted by the Korea Polar Research Institute (KOPRI) to develop a prototype of a quasi-real time weather/climate prediction system for data collection, model initialization, forecast, evaluation, and visualization in a web environment. The prototype system will be of tremendous value to the weather/climate prediction society in Korea and lead to improve weather/climate forecasts which will allow all citizens to make better decisions in the short-, medium- and possibly long-term future.  It will also be an excellent tool for students to understand the overall modeling process system.

COAPS featured at Innovation Park's "TechTopics" luncheon
COAPS Director Dr. Eric Chassignet, State Climatologist  Dr. David Zierden, and COAPS alum Dr. Mark Powell were featured speakers at the March 2016 TechTopics luncheon in Tallahassee, FL. The TechTopics Series (formerly known as Industry Sector Roundtables), focuses on the unique research assets and commercialization opportunities specific to the city's Innovation Park. Dr. Chassignet gave an overview of the research being conducted by COAPS researchers, while Dr. Zierden presented on the 2016 Super El Nino and how it impacts climate and extreme weather in Florida. Dr. Powell gave an update on the work being conducted by HWind Scientific, a real-time hurricane data company.
FSU Day at the Capitol 
The annual  FSU Day at the Capitol, held this year on February 2, was an opportunity to celebrate the university's recent successes and contributions. Inside the Capitol, FSU showcased its academic excellence with information booths representing the university's academic programs and research centers, including COAPS.

Sean Buchanan (B.S. student, Meteorology) has been awarded a 2016 IDEA Grant by the FSU Center for Undergraduate Research and Academic Engagement (CRE).  Buchanan's research project, entitled "
Reconstructing historical Integrated Kinetic Energy (IKE) of Atlantic Tropical Cyclones," will extend the database of the IKE for Tropical Cyclones (TCs) within the Atlantic and expand the database for TCs in other tropical ocean basins. The IKE of a TC is the integration of the square of the winds around the center of the TC and outward till the wind speed drops below strength of tropical storm. Unlike the Saffir Simpson (SS) wind scale of TC, which is based on empirically measured 1 minute sustained wind speed at a specific location and instant of time of a TC, IKE uses size of the TC and integrates the wind around the center, making it more representative of the destructive potential of a TC than the SS scale. Learn more about the IKE index.

T. Karmel 
Tom Karmel (B.S. student, Meteorology) successfully defended his undergraduate honors research, "Using multiple methodologies to explore variation in rainfall events in the southeastern United States."  The primary goal of his research is to investigate the change in rainfall in the southeastern U.S. by analyzing extreme precipitation on a local station scale and to examine the distribution of non-extreme rainfall events for changes in time and due to large-scale changes such as ENSO. 
Educational Outreach
COAPS showcases science (and fun!) at annual open house    
COAPS' annual open house is designed to stimulate public knowledge about science, particularly the kind of science being conducted at COAPS. This year's open house was attended by nearly 800 visitors and featured something for everyone... hands-on science fun, self-guided tours, and the chance to meet and interact with our scientists. Attendees learned how drones are used to observe the earth, about rising seas, marine data, and how COAPS researchers are modelling the ocean and atmosphere. They were able to drive an underwater robot, and to see and touch live sea creatures (thanks to our colleagues in the FSU Biology Department's Sea-to-See program) 
"W" is for weather

Students at Tallahassee's Growing Room Learning Center have been learning about weather.  So they invited COAPS'  Danielle Groenen, PhD student in Meteorology, to visit the center on March 29 and share some fun with science!  Ms. Groenen demonstrated the power of wind, made a cloud in a bottle, and everyone had fun doing the Water Cycle Boogie.
