The role of the Federal Government in Meteorology: The role of the Federal Government in Meteorology The mission of the Meteorological Service of Canada is to anticipate and respond to the evolving needs and expectations of Canadians and their institutions for meteorological, hydrological and related information and prediction services thereby helping Canadian adapt …in ways which safeguard their health and safety, optimize economic activity and enhance environmental quality. –source MSC.
…in 2010, the eyes of the world will be on Canada as Vancouver and Whistler host the winter Olympics, an opportunity to inspire Canadian pride and achievement… - source the Hon. Adrienne Clarkson, speech from the Throne, 2 February 2004

What defines the requirements for weather support?: What defines the requirements for weather support? The SLC experience – significant investments in observations, modeling and forecasting.
“It's critical to the games to be able to have accurate weather forecasts on basically a minute-by-minute basis. We need to know whether spectators should come up to a venue and....to determine whether there's any risk of avalanche or any other kind of problem like that. We also need to make sure that the skiers and snowboarders and other participants know exactly what the conditions will be so we can determine whether to maintain an event or cancel it, postpone it, based upon weather considerations. So it's....it's essential to the Games to have accurate weather forecasting”
- Mitt Romney, President and CEO, Salt Lake Organizing Committee
What’s the difference between SLC and Vancouver/Whistler?: What’s the difference between SLC and Vancouver/Whistler? The weather is:
Worse.
Harder to forecast.
Not enough data.
Topography is complex.
Partnership challenges.
Partnership challenges: Partnership challenges SLC weather partners included:
NBC TV (14 forecasters at the venues)
U of Utah (computer modeling and data management)
NWS (broad-scale forecasts and warnings)
State Gov’t of Utah (financial support and data)
Other Federal Departments (data and $$)
2010 weather partnerships?: 2010 weather partnerships? Limited private sector capacity for weather forecasting in Canada.
No local private sector forecasting expertise.
Limited Provincial resources.
University partnerships a possibility – they do have local expertise in modeling
Slide8: Topographical challenges
Topography of the Lower Mainland and Sea-to-Sky: Topography of the Lower Mainland and Sea-to-Sky Highly variant
Creates differing weather conditions over short scales of distance, altitude and time – a 4 d forecast problem most of the Rest of Canada doesn’t have.
Inadequately observed.
Creates weather surprises (forecast for Whistler Thursday Jan 29th- Friday 5-10 cm snow. Observation 41 cm.
Data ChallengesSLC 2002 – 80+ observations within 50 km 250+ within 200 km: Data Challenges SLC 2002 – 80+ observations within 50 km 250+ within 200 km
Slide11: Data Challenges:
Vancouver Whistler 2010: currently 31 reliable but incomplete observations within 100 km
Other Data challenges: Olympic Venues: Other Data challenges: Olympic Venues Current data set is limited
Requirements range from sophisticated to basic – depends on event requirements (SLC experience)
Coverage of the venues alone is NOT adequate for 2010 forecasting

Weather ImpactsFebruary 2002October 2003: Weather Impacts February 2002 October 2003
Severe winter Storms. A “pineapple express” doused the south coast with heavy rain on Feb 21/22. Amounts in the greater Vancouver area ranged from 40-60mm ( 53.0 at Vancouver Cypress rising to 92 mm at Hope, 89 mm at Squamish). This system dumped 40 cm of snow on Whistler in 24 hours.
Major Flooding. October 2003 brought a rainfall event that flooded homes in Squamish and destroyed a highway and railway bridge near Pemberton. 4 Deaths are attributed to the storm with millions of $ in property and infrastructure damage.
Weather ImpactsMarch 2003: Weather Impacts March 2003
March 7th -… Snowstorm in Southern BC…30 to 50 cm on Coquihalla – major closure of highway. School bus slid off highway near Revelstoke injuring 12 students, numerous accidents in the eastern Fraser Valley including a 7 car pileup near Hope.
March 8th – snow in lower mainland & east Vancouver Island.
March 11 – Avalanches cause major closure of Trans Canada between Revelstoke and Lake Louise. Avalanche rating for entire province “extreme”
March 13 – Wind and rainstorm wreaks havoc on Vancouver Island
Summary of requirements (1): Summary of requirements (1) There are 5 winters remaining before the Games begin.
To deliver a high quality service with minimal surprises we need :
At least 25 additional observing sites (6 venue sites plus 19 others) ASAP.
We need to begin gathering data and developing models this summer.
Summary of Requirements (II): Summary of Requirements (II)
Next, we need to develop:
a data assimilation system,
a high resolution modeling system,
venue specific weather data,
information telecommunications, and
To do basic research on high-impact weather at the venue, communities and corridor.
Olympic forecasting – What needs to be done (1): Olympic forecasting – What needs to be done (1) Regional and venue surface observing network design and implementation
Local and regional data assimilation project- putting the data to work
Real-time modeling – feeding the data to computers and training them to produce helpful weather guidance
Development of statistical forecasting aids
What needs to be done (II): What needs to be done (II) Development of forecast team and Olympic dissemination network and systems

Decisions: Decisions Our own preliminary studies and the SLC model suggest we need to add a ~25 station weather observing network this summer.
We need a commitment from the 2010 OC to acquire the instrumentation and to provide resources for installation to the extent possible.
We need to work out a weather services agreement with the OC – but getting data is critical and time is of the essence. The longer we go without data the less skill we will have.
We are approaching the Federal Cabinet this year for additional funding but the decision making process will not be completed until fall 2004 at the earliest.
