JCOMM Technical Report, 56. JCOMM Expert Team on Sea Ice (ETSI): 3rd Ice Analysts’ Workshop
Ice (ETSI), Dr. Vasily Smolyanitsky (Russian Federation), at 0900 hrs on Tuesday 18 June 2011 at the Danish Meteorological Institute, Copenhagen, Denmark. Dr. Smolyanitsky noted that the Ice Analysts’ Workshops are endorsed by both JCOMM and the International Ice Charting Working Group (IICWG) as being a valuable forum to share knowledge and coordinate ice information services throughout the world. Recognizing the increasing navigation that is taking place in the Arctic, five new METAREAs were created 3 years ago to ensure that Marine Safety Information (MSI) through the Global Global Maritime ...
JCOMM Technical Report, 59. Proceedings of the third International workshop on advances in the use of historical marine climate data
Marine surface observations—which represent a vital component of the Global Climate Observing System (GCOS)—are key to understanding global climate, including its variability on time scales ranging from sub-daily to weekly to centuries. Prior to 1970, ships were almost the only source of observations. In the modern era, sensors deployed on ships, moored and drifting buoys, aircraft, and Earth Observation (EO) satellites all provide surface measurements of many different variables. The Third International Workshop on Advances in the Use of Historical Marine Climate Data (MARCDAT-III) was hosted ...
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 ...
CAWCR technical report, 40. Comparison of techniques for the calibration of coupled model forecasts of Murray Darling Basin seasonal mean rainfall
Charles Andrew; Hendon Harry H.; Wang Q.J.; et al. - Centre for Australian Weather and Climate Research, 2011Ensemble forecasts of South Eastern Australian rainfall from POAMA 1.5, a coupled oceanatmosphere dynamical model based seasonal prediction system run experimentally at the Bureau of Meteorology, tend to be under dispersed leading to overconfident probability forecasts. The poor reliability of seasonal forecasts based on dynamical coupled models is a barrier to their adoption as official outlooks by the Bureau of Meteorology. One approach to correcting this problem is model calibration, in which the probability distribution produced by the model is adjusted in light of available information ab ...
GAW Report, 202. Workshop on Modelling and Observing the Impacts of Dust Transport/Deposition on Marine Productivity
In this report we evaluate the state-of-art knowledge and uncertainties regarding the deposition of dust on the ocean and its mineralogical composition provided by models and measurement datasets. Global climate models were recently intercompared by Huneeus et al. (2011) using results from the AEROCOM model intercomparison. The deposition calculations from these global models are frequently used as input for biological productivity calculations. A model measurement comparison (Huneeus, 2011) shows that global models do reproduce the observed data over several orders of magnitude. However, the ...
Tsunami Strike! Pacific Edition
Tsunami Strike! Pacific Edition is a scenario-based learning experience for kids from middle school through high school (approximate ages 13-17). The scenario tells the story of four main characters at different locations in the Pacific basin who are each impacted by a major tsunami that originates in Alaska’s Aleutian Islands. Over the course of the story, learners not only view the unfolding events and how each of the characters responds, but also observe how warning scientists analyze and communicate the tsunami threat. Fourteen short lessons provide interactive instruction focused on the s ...
Sea Ice and Products and Services of the National Ice Center
This two-hour module examines sea ice, icebergs, and the products and services of the National Ice Center and the North American Ice Service.

Volcanic Ash: Impacts to Aviation, Climate, Maritime Operations, and Society
This module is the third in the four-part Volcanic Ash series. It provides information on the impacts of an explosive volcanic eruption to aviation, climate, maritime operations and society. The threats, or impacts, from an eruption vary depending on the eruption style, duration and proximity--both in distance and altitude--to the volcano. As you learned earlier, an eruption may bring multiple hazards to urban and rural areas through: Lahars (mudflows) and floods Lava-flow inundation Pyroclastic flows and surge Volcanic ash and bomb fallout Volcanic gases In this module, we'll take a closer lo ...
Coastal Climate Change
As climate changes, dynamic coastal regions are experiencing a wide range of impacts. Sea levels, ocean acidification, sea surface temperatures, ocean heat, and ocean circulation have all been changing in ways unseen for thousands of years. Arctic sea ice melted significantly more during summers in the last 30 years, and storms are intensifying. Coastal ecosystems stand to be damaged, and coasts will likely erode from rising sea levels, intensified storm surges, and flooding that climate change may amplify. Coastal communities will need to prepare adaptation strategies to cope, and many who li ...
Volcanic Ash: Introduction
Provides a concise introduction to volcanic ash through the examples of the Mt. Pinatubo and Eyjafjallajökull eruptions. This is the introduction to a four-part series on Volcanic Ash.
Introduction to Tropical Meteorology, 2nd Edition, Chapter 3: Global Circulation
The chapter begins with a review of the general principles of atmospheric motion including scale analysis of tropical motions. An overview of the general circulation of the atmosphere and ocean is presented including stratospheric general circulation. Special emphasis is given to the Hadley circulation including its maintenance, seasonal migration, northern and southern hemispheric differences, and the contrast between tropical and midlatitude wind systems. Tropical circulations are examined in a theoretical framework as responses to heating at the equator. Regional monsoons, their conceptual ...
Ocean Observations Panel for Climate, Interview with Eric Lindstrom: in International Innovation, August 2011
NASA, 2011The more research carried out on our oceans, the more significant its role has proven in the broader climate system. Observing Earth’s Ocean System is therefore a vital component of climate research, and the OOPC is working hard to direct this effectively, as its Chair Dr Eric J Lindstrom explains.

Blue carbon policy framework 2.0 : based on the discussion of the International Blue Carbon Policy Working Group
Development and implementation of blue carbon-based activities now requires strategic policy and incentive mechanisms to achieve coastal conservation, restoration and sustainable use, and provide disincentives to drain or damage coastal systems. A first effort to develop such a strategic program was set out in the first edition of the Blue Carbon Policy Framework. Based on additional information and current progress a revised Blue Carbon Policy Framework 2.0 has now been developed. It updates the previous version and adds a detailed coordinated program of policy objectives and activities. It o ...
