Dr. Hartmann is a national leader in research related to the development of decision support tools for climate, water, and other resource management applications, especially linking research with the needs of decision-makers and moving research into agency operations. Dr. Hartmann is Carpe Diem West’s Director of Climate Science Applications. Previously she was Director ...Climate and Water Resources Management, Part 1: Climate Variability and Change
Climate is changing at unprecedented rates in recorded history. A variety of lines of evidence demonstrate that climate change is likely to affect the hydrologic cycle and thus create new challenges in water management. This requires that climate change information be included in water and water-related resources planning, operations, and management. Climate and Water Resources Management, Part 1: Climate Variability and Change describes the terminology, global evidence, regional manifestations, and basic science of global climate variability and anthropogenic change, with a focus on water res ...Typhoon QPF in Taiwan
This lesson (available in Chinese) introduces the typhoon QPF forecasting methodology used by the CWB, including the role played by the analogue method and the typhoon rainfall climatology model in Taiwan. The lesson discusses the advantages and limitations of the Ensemble Typhoon QPF model, and includes a case to help learners practice interpreting this guidance and summarizing it to Emergency Operation Centers. The lesson also highlights the need to use probabilistic forecasts instead of deterministic forecasts in order to account for the uncertainties associated with typhoon forecasting.Forecasting Mountain Wave Turbulence for Aviation
Turbulent flow that impacts aviation can be caused by several different factors and can occur at both low and high-levels in the atmosphere. This lesson focuses on forecasting mountain wave turbulence. Its methodology relies on the spatial and temporal distribution of winds, stability, and clouds to forecast and verify mountain wave turbulence. Analyzed forecast products include NWP charts, cross sections and soundings, satellite imagery, RAOBs, PIREPS, and graphical turbulence guidance (GTG). The lesson is targeted for aviation forecasters at the U.S. National Weather Service (NWS). The modul ...Using NWP Lightning Products in Forecasting
This lesson introduces two numerical weather prediction (NWP) lightning hazard products that forecasters can use during a convective meteorological watch and to assess lightning risk at Day 2 and beyond. The first product is the Flash Rate Density, a derived, deterministic lightning product implemented in some NCEP high-resolution NWP models. The second product, the SPC Calibrated Thunderstorm Probability, combines forecasts of measurable precipitation and favorable lightning environments determined from the Cloud Physics Thunder Parameter. Information about these products is presented in the ...SatFC-G: Basic Principles of Radiation
This lesson is an abbreviated review of the scientific basis for using visible and infrared satellite imagery.

Although previous research suggests that we are not very good at reasoning with uncertainty, the research described in this talk is far more encouraging. Unlike earlier work that compares peoples' decisions to a rational standard, these experiments compared decisions made by people with uncertainty information to decisions made by people without uncertainty information. The results suggest that including specific numeric uncertainty estimates in weather forecasts leads to better decisions. This talk was part of Meteorological Service of Canada's 2015 Workshop on Communicating Uncertainty to Us ...
