This module presents radar case studies taken from events in the Caribbean that highlight radar signatures of severe weather. These cases include examples of deep convection, squall lines, bow echoes, tornadoes, and heavy rain resulting in flooding. Each case study includes a discussion of the conceptual models of each type of event as a review before showing the radar signatures and allowing the learner to analyze each one.
Workshop on Regional & Global Exchange of Weather Radar Data: final report
The aims and objectives for the workshop had been approved by ICT-IOS-7 in July 2012 and CBS-XV in September 2012. However the challenge was substantial as: the user community has varied and evolving requirements; the operating communities have a wide range of technological, political and financial challenges and there are already numerous successful bi-lateral and multi-lateral exchange agreements already in place. Understanding the current situation in terms of requirements, exchange agreements and constraints is an issue in itself. But this will be necessary in order for the next step actio ...Weather Radar Fundamentals
This 2-hour module presents the fundamental principles of Doppler weather radar operation and how to interpret common weather phenomena using radar imagery. This is accomplished via conceptual animations and many interactive radar examples in which the user can practice interpreting both radar reflectivity and radar velocity imagery. Although intended as an accelerated introduction to understanding and using basic Doppler weather radar products, the module can also serve as an excellent refresher for more experienced users.CAWCR technical report, 45. Evaluation of the TIGER SuperDARN Over-The-Horizon radar systems for providing remotely sensed marine and oceanographic data over the Southern Ocean
Greenwood Robert; Schuiz Eric; Parkinson Murray; et al. - Centre for Australian Weather and Climate Research, 2011The Tasman International Geospace Environment Radar systems (TIGER) located in Tasmania and New Zealand are High Frequency (HF) Over-The-Horizon Radar (OTHR) systems and represent Australia’s contribution to the Super Dual Auroral Radar Network (SuperDARN). SuperDARN is a network of more than 20 HF radars located at mid-high latitudes with fields of view covering the polar regions for the study of ionospheric physics. The TIGER systems have overlapping fields of view that cover much of the Southern Ocean in the Australian sector. The development and operation of TIGER has been led by La Trobe ...Radar Signatures for Severe Convective Weather
This resource is intended for use as a job aid by operational weather forecasters in live warning situations and as a reference tool to better understand some aspects of severe thunderstorm warning events. Thumbnail images show typical representatives for sixteen radar reflectivity and velocity signatures as well as three primary severe storm types. Each signature links to content describing detection techniques and conceptual and diagnostic information to help determine storm severity. The majority of the examples shown are southern hemisphere storms in Australia; examples from the northern h ...Introduction to Tropical Meteorology, 2nd Edition, Chapter 2: Tropical Remote Sensing Applications
This chapter covers remote sensing, the primary method of observing weather and climate across the global tropics. Learners will become familiar with the scientific basis and applications of radar and satellite remote sensing from examples in which clouds and precipitation are observed by measuring microwave signals using ground-based radar, spaceborne radar, and satellite radiometers. Wind estimation, dust and volcanic ash tracking, vertical sounding techniques, and remote measurement of sea-surface, soil and land surface properties are also covered.Precipitation Estimates, Part 2: Analysis
This is part two of a two-module series on estimation of observed precipitation. Through the use of rich illustrations, animations, and interactions, this module provides an introduction to the science behind successful application of the products and tools available through the NWS Multisensor Precipitation Estimator (MPE) software and related products. An overview is presented of the key fields available in MPE along with illustrations of their use. These include radar, gauge, satellite, bias-adjusted radar, and multisensor fields of precipitation accumulation along with data displays and ta ...Precipitation Estimates, Part 1: Measurement
This is part one of a two-module series on estimation of observed precipitation. Through use of rich illustrations, animations, and interactions, this module provides an overview of the science of precipitation estimation using various measuring platforms. First, we define quantitative precipitation estimation (QPE) and examine technologies for remote sensing of QPE, including radar and satellite and the strengths and limitations of each. That is followed by an examination of the use of rain gauges for precipitation estimation and important issues to consider with rain gauge measurement. Final ...Jason-2: Using Satellite Altimetry to Monitor the Ocean
Altimeters onboard satellites such as Jason-2 measure sea surface height and other characteristics of the ocean surface. These characteristics are linked to underlying processes and structures, making altimetry data useful for understanding the full depth of the global ocean. This 75-minute module explores major discoveries made possible by altimetry data in oceanography, marine meteorology, the marine geosciences, climate studies, the cryosphere, and hydrology. For example, altimeters have played a vital role in detecting and monitoring sea level rise and its relation to climate change. The m ...Lectures on Radar Applications in Mesoscale Meteorology
This website provides access to the streaming presentations and PowerPoint source files for the 11 lectures delivered during the AMS Educational Forum “A Primer on Radar Analysis Techniques Used in Mesoscale Meteorology” held on 23 October 2005 in Albuquerque, NM. The presentations discuss how many advanced techniques for the analysis of meteorological radar data can be used to improve understanding of the structure, dynamics, and evolution of mesoscale circulations. The Forum was organized into four sections: 1) Microphysical Characterization of Precipitation Systems Using Dual-Polarization R ...
