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 ...
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. Topics include climatology and current trends in sea ice extent and thickness; the development, classification, and drift of sea ice and icebergs; fractures, leads and polynyas; and the satellite detection of sea ice using visible, infrared, and microwave sensors.
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 ...

An Arctic Sea Ice Simulation Using an Ocean-Ice Coupled Model
Atmospheric and Oceanic Science Letters, Volume 3 Number 4. Sun Hong-Chuan; Zhou Guang-Qing - Science Press, 2010This paper evaluates the simulation of Arctic sea ice states using an ocean-ice coupled model that employs LASG/IAP (the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics/ the Institute of Atmospheric Physics) Climate Ocean Model (LICOM) and the sea-ice model from the Bergen Climate Model (BCM). It is shown that the coupled model can reasonably reproduce the major characteristics of the mean state, annual cycle, and inter-annual variability of the Arctic sea ice concentration. The coupled model also shows biases that were generally pre-sented in ...
A Forecaster's Overview of the Northwest Pacific
This module provides an introduction to the northwest Pacific for weather forecasters. It touches on major aspects of the geography, oceanography, and climatology. Geography looks at plate tectonics, topography, and human population. Oceanography examines ocean currents, coastal tidal ranges, and sea ice distribution. Climatology briefly discusses jets streams, distribution of synoptic features, storm tracks of tropical and extratropical cyclones, the fronts, and sensible weather associated with the Northeast and Southwest Monsoons.
JCOMM Technical Report, 23. SIGRID-3 :a vector archive format for sea ice charts
Intergovernmental Oceanographic Commission (IOC); World Meteorological Organization (WMO) ; International Ice Charting Working Group's Ad Hoc Format Team for the WMO Global Digital Sea Ice Data Bank Project - WMO, 2010 (revised edition; WMO/TD-No. 1214)This document describes the SIGRID-3 format so that it may be understood by a variety of users and implemented by chart-producing ice centers or services. SIGRID-3 evolved from earlier SIGRID formats and incorporates much of their content (see Appendix 1 for notes on earlier SIGRID formats and their application in SIGRID-3). For example, SIGRID variable identifiers such as “CT” for total concentration are used in SIGRID-3. While all SIGRID variable identifiers may be used in SIGRID-3, those that are commonly used are required, such as concentration, stage of development, and form. Users famili ...
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 ...
