Principles of Convection III: Shear and Convective Storms
This module discusses the role of wind shear in the structure and evolution of convective storms. Using the concept of horizontal vorticity, the module demonstrates how shear enhances uplift, leading to longer-lived supercell and multicell storms. The module also explores the role of shear in the development of mesoscale convective systems, including bow echoes and squall lines. Most of the material in this module previously appeared in the COMET modules developed with Dr. Morris Weisman. This version includes a concise summary for quick reference and a final exam to test your knowledge. The m ...
The El Niño-Southern Oscillation (ENSO) Cycle
This Webcast, is an expert lecture by Dr. Vernon Kousky of NOAA/CPC, entitled "The El Niño-Southern Oscillation (ENSO) Cycle". The presentation covers the identification and global weather impacts associated with both phases of ENSO. This version of the presentation has enhanced graphics and has been modified to include an introduction to the newly established “Operational Niño Index” (ONI). A forecaster who attended the original classroom presentation on The ENSO Cycle had the following to say... “[This lecture was the] best presentation of the workshop! Very comprehensive, from the basics to ...
Operational hydrology report (OHR), 48. Hydrological Data Management: present state and trends
This report details the present state and trends in constructing data-bases for hydrological data, the real-time utilization of the data and the application of Geographical Information Systems (GIS) to operational hydrology in various countries.

Integrated Global Carbon Observing Strategy (IGCO) - "a strategy to build a coordinated operational observing system of the carbon cycle and its future trends" : IGCO version 4.3/12/2003
Carbon cycle research is often carried out in isolation from research on energy systems and normally focusses only on the biophysical patterns and processes of carbon sources and sinks. The Global Carbon Project represents a significant advance beyond the status quo in several important ways. First, the problem is conceptualised from the outset as one involving fully integrated human and natural components; the emphasis is on the carbon-climate-human system (fossil-fuel based on energy systems + biophysical carbon cycle + physical climate) and not simply on the biophysical carbon cycle alone. ...

Thermally-forced Circulation I: Sea Breezes
This module describes the phenomena of the sea breeze. It examines factors that lead to the formation of a sea breeze, modifying effects on sea breeze development, how mesoscale NWP models handle sea breezes, and sea breeze forecast parameters. The module places instruction in the context of a sea breeze case from Florida and compares surface and satellite observations to a model simulation using the AFWA MM5. Like other modules in the Mesoscale Meteorology Primer, this module comes with audio narration, rich graphics, and a companion print version.
Principles of Convection I: Buoyancy and CAPE
This module provides a brief overview of Buoyancy and CAPE. Topics covered include the origin of atmospheric buoyancy, estimating buoyancy using the CAPE and Lifted Index, factors that affect buoyancy including entrainment of mid-level air, water loading, convective inhibition, and the origin of convective downdrafts. This module delivers instruction with audio narration, rich graphics, and a companion print version.
Thermally-forced Circulation II: Mountain/Valley Breezes
This is a foundation module in the Mesoscale Meteorology Primer series. Topics covered include up- and downslope breezes, up- and down-valley winds, associated hazards, and forecasting techniques. Like other modules in the Mesoscale Meteorology Primer, this module comes with audio narration, rich graphics, and a companion print version.
How Mesoscale Models Work
The goal of this training module is to help you increase your understanding of how mesoscale models work. Such understanding, in turn, can help you more efficiently and accurately evaluate model-generated forecast products.

IPCC Special Report. Methodological and Technological Issues in Technology Transfer
World Meteorological Organization (WMO) ; United Nations Environment Programme (UNEP); Intergovernmental Panel on Climate Change (IPCC) - IPCC, 2000Effective global response to climate change requires the development and transfer of environmentally sound technologies between and within countries, both for adapting to climate change as well as for mitigating the effects of greenhouse gas emissions. This IPCC Special Report provides a state-of-the-art overview of how to achieve and enhance this transfer. 185 eminent experts from around the world provide accurate, unbiased, policy-relevant information on technology transfer, such as capacity building, the promotion of an enabling environment, and mechanisms for technology transfer from devel ...
