Research interests: Regional Climate and Hydrology, Climate Change Impacts

Norm Miller is an Adjunct Geography Professor and Staff Scientist at the UC Sierra Nevada Research Institute. He is focused on understanding hydroclimate processes and related impacts based on modeling and analysis of regional climate and hydrology and their impacts on water supply and demand, water quality, agriculture, and impacts to other sectors of society. This includes, coupled atmosphere- land surface-groundwater modeling from the site scale to continental scale; climate variability and change analyses; water and energy resources impacts, scaling theory; nonlinear coupling, feedbacks and sensitivities with climate systems; and high performance computing.

The Berkeley Hydroclimate Group investigates past, present, and future climate on regional and sub-regional spatial scales and at temporal resolutions representative of weather and climate. Our research includes conceptual models, numerical code development and evaluation, statistical analyses of historical and projected global and regional climate, numerical weather and streamflow ensemble prediction, seasonal forecasts, and scaling theories. We use remote-sensed observations, reanalysis data, and IPCC AOGCM projections as input forcing to our limited area models and statistical downscaling schemes to understand climate and impacts at site-to-regional scales.

Geography 171: Climates of the World

Fall 2014, Tuesday and Thursday, 2:00 - 3:30

145 McCone

We begin with an overview of very basic atmospheric dynamics and physics at the large scale, followed by region-specific climate systems. We will look at regional responses to climate change and the inter-relationships between the role of climate variations and impacts. Class often begins with a weekly weather in review that focuses on a specific geographic region and may include societal impact discussions. There will be two exams and a final project that incorporates basic climate principals and regional climate change impacts. This year the xams will be structured for short answer and schematic understanding. Prerequisites: High school level physics. This is not a math-based climate class.


Civil and Environmental Engineering 203: Surface Hydrology

Fall 2014, Tuesdays and Thursdays 11:00 - 12:30

This course will be split into three parts (1) conservation equations and water in the atmosphere, (2) Navier-Stokes and St. Venant equations, and water on the surface, and (3) case studies and model-based analyses. Each Tuesday will begin with a brief review and each Thursday will begin with a paper review that highlights the material being discussed. There will be two midterms each at 25% of the total grade, a project at 25%, six homework problem sets at 3% each, and class participation at 7%. Office hours are Tuesday and Thursday from 3:30-5:00.
