How do climate variations and climate change affect weather events and vice-versa?

National Weather Service:Collaborating on Climate Services
Goals/Objective
Support CS vision/mission Key challenges:
Climate/Weather linkage for short term predictions
Production of climate information to meet national, regional and local needs
User engagement User requirements and service delivery Preparedness vs Adaptation
Training/education of workforce

Climate Responsibilities of NWS and CS
Societal Action DominatesPersonal Action DominatesLow Freq of InformationLong Lifetime of Product
High Freq of InformationShort Lifetime of Product
NWS Climate Responsibilities
Deliver climate prediction, monitoring , and assessment products and services to support response and preparedness , including related applied research and modeling to improve capabilities
Understand and predict the influences of climate on weather events to deliver seamless prediction
Mission: More short-term response and preparedness (i.e. non permanent actions to respond to and prepare for infrequent threats such as, floods, hurricanes, El Niño).
Early warning; more accurate information; less uncertainty
Shared Strategic Challenges
Improved understanding and ability to simulate and predict the relationship between climate variation and extreme events
NWS monitoring and assessment of variability will provide information to CS assessments of decadal climate change
CS assessments of climate change forcing of variability will provide information to NWS predictions
CS
Provide assessment services and projections, and research to improve predictions and projections
Mission: More long term adaptation and mitigation related (e.g. Are floods affecting a community more frequently? Are they more intense? What actions can be taken?)
CS also addresses mitigation of climate change, a distinct difference between NCS and NWS
