CAWCR technical report, 61. Improvements in atmospheric physical parameterizations for the Australian Community Climate and Earth-System Simulator (ACCESS)
The Australian Community Climate and Earth-System Simulator (ACCESS) is a new coupled ocean and atmosphere climate modelling system being developed at the Centre for Australian Weather and Climate Research (CAWCR). ACCESS uses the UK Met Office Unified Model (Met UM, Davies et al. 2005) as its atmospheric component, which is coupled with the GFDL Ocean Model version 4.1 (MOM4p1, Griffies et al. 2009) and the Los Alamos National Laboratory Sea Ice Model version 4.1 (CICE4, Hunke and Lipscomb 2010), using the numerical coupler OASIS3.25 (Valcke 2006). The development of ACCESS has followed ...
Climatology for the Operational Forecaster
Climate information can be used as guidance for a range of weather-dependent operations. This module summarizes the Climate Analysis Process, a series of steps for determining which climatological products and data will be most useful for a specified application. The Climate Analysis Process is followed in the context of preparing a climatological brief for a ship deployment across multiple ocean basins. Though the focus is on Department of Defense data sources, including the Advanced Climate Analysis and Forecasting (ACAF) system, information on other sources is also provided. Products from t ...
JCOMM Meeting Report, 94. Fourth session of the Expert Team on Marine Climatology (ETMC): Final Report
The fourth session of the Expert Team on Marine Climatology (ETMC) was held at the Project Office of the International Oceanographic Data and Information Exchange (IODE) of the Intergovernmental Oceanographic Commission (IOC) of UNESCO, Ostend, Belgium, from 26 to 28 November 2012. Members of the Task Team on the Marine Climate Data System (MCDS) were also invited to the meeting as MCDS was high in the agenda for this meeting.
The main goals of the meeting were to address guidance from the fourth session of the Joint WMO-IOC Technical Commission for Oceanography and Marine Meteorology ( ...

Preparing Hydro-climate Inputs for Climate Change in Water Resource Planning
This lesson describes the process of selecting the best available climate projection information and using it to develop “climate-adjusted weather” inputs to be used for modeling climate change impacts. These modeled impacts can be used for planning of future water resources. Specific steps of this process include: 1) Recognizing the general science and terms associated with Atmosphere-ocean General Circulation Models (AOGCMs); 2) Making AOGCMs more regionally applicable through bias correction and downscaling; 3) Determining climate change scenarios based on climate projections and selecting ...
Arctic Meteorology and Oceanography
Diminishing sea ice has opened the Arctic to navigation and operations like never before. Forecasters are increasingly predicting weather in support of those operations. This module is intended to provide forecasters with a brief introduction to the Arctic, including its geography, climatology, and the forecast problems they are likely to encounter. The module follows a U.S. Coast Guard Cutter on a voyage from Dutch Harbor, in the Aleutian Islands, to Barrow, on the north coast of Alaska. Various topics are addressed along the way in a series of short, stand-alone lessons.
Technical Report Series, 01. Climate and Meteorological information requirements for water management : a review of issues
In providing better understanding between climate and water management, this review will, where relevant, adopt the approach of a SWOT analysis (strengths, weaknesses, opportunities and threats). As well as some recent initiatives noted in the preceding section, the basic data requirements and methods for water management are covered in the WMO Guide to Hydrological Practices (Ref. 7). In Volume I, Chapters 2, 3 and 4 deal with the climate observations required for water management, whilst Volume II deals with applications and management activities. Table II.4.1 from that publication is a part ...

Reconciling anthropogenic climate change with observed temperature 1998–2008
Given the widely noted increase in the warming effects of rising greenhouse gas concentrations, it has been unclear why global surface temperatures did not rise between 1998 and 2008. We find that this hiatus in warming coincides with a period of little increase in the sum of anthropogenic and natural forcings. Declining solar insolation as part of a normal eleven-year cycle, and a cyclical change from an El Nino to a La Nina dominate our measure of anthropogenic effects because rapid growth in short-lived sulfur emissions partially offsets rising greenhouse gas concentrations. As such, we fin ...
Climate for you
Through a wide variety of proxy records, including ice cores, tree rings, sediments, corals, rocks and fossils, among others, the modern science of paleoclimatology reveals that climate variability and change were present on our planet long before our ancestors. More recently, there are several references in our recorded history to unusual periods in some parts of the world, such as the Medieval Climatic Anomaly and the subsequent Little Ice Age, as well as exceptional events like the “year without a summer” of 1816, attributed to the colossal 1815 Mount Tambora eruption.

Sécurité des moyens d’existence : changements climatiques, migrations et conflits au Sahel
PNUE, 2011Cette étude commune à paraître a deux objectifs : premièrement d’analyser l’évolution historique du climat dans le Sahel, d’identifier les régions où des problèmes se posent avec une acuité particulière (nommées « points chauds ») et de déterminer les implications potentielles des variations climatiques observées sur les moyens d’existence dépendants des ressources naturelles ; deuxièmement de fournir des recommandations destinées à améliorer la sensibilité des plans d’adaptations et d’investissement de la région aux problématiques de conflit et de migration.
Le climat et vous
Grâce à la paléoclimatologie moderne et au large éventail de données indirectes qu’elle recueille dans les carottes de glace, les cernes d’arbres, les sédiments, les coraux, les roches et les fossiles, nous savons que le climat de notre planète se caractérisait déjà par sa variabilité bien avant que
nos ancêtres n’apparaissent. Plus récemment, les références de l’histoire font état aussi de plusieurs périodes inhabituelles dans différentes régions du monde, notamment l’anomalie climatique médiévale, suivie du petit âge glaciaire, ou
encore de phénomènes exceptionnels comme «l’ann ...
Климат для вас
с помощью большого разнообразия косвенных данных, включая, среди прочего, керны льда, годичные кольца деревьев, осадочные отложения, кораллы, горные породы и ископаемые остатки, современная наука палеоклиматология показывает, что изменение и изменчивость климата имели место на нашей планете задолго до наших предков. В последнее время в документируемой истории появлялся ряд ссылок на необычные периоды в некоторых районах
мира, такие как средневековая климатическая аномалия и более поздний малый ледниковый период, а также на такие исключительные события, как 1816 г. — «год без лета», ...
El clima y tú
gracias a una gran diversidad de registros indirectos, como núcleos de hielo, anillos de árboles, sedimentos, corales, rocas y fósiles, entre otros, la moderna ciencia de la paleoclimatología ha demostrado que la variabilidad y el cambio climáticos estaban presentes en nuestro planeta desde mucho antes que nuestros ancestros. más recientemente, nuestros registros históricos parecen indicar varios períodos inhabituales en ciertas partes del mundo, como la anomalía
climática medieval y la pequeña era glacial subsiguiente, y también períodos excepcionales, como el “año sin verano” de 1816 ...
Techniques in Hydrologic Forecast Verification
This module demonstrates techniques for developing a hydrologic forecast verification effort. Although it can be taken as stand-alone training, the module on Introduction to Verification of Hydrologic Forecasts is intended a useful prerequisite. Through the use of rich illustrations, case study examples, and review questions, this module provides an example of developing a verification effort using NWS verification tools. Two case studies will be highlighted that both look at the primary question of whether QPF input to hydrologic models improves the hydrologic forecasts. Related questions of ...
