Meteorological Society of New Zealand Newsletter - June 2011 - Page 3 Annual Conference Monday 14 November – Tuesday 15 November 2011 Trailways Hotel 66 Trafalgar Street, Nelson AIM The aim of the meeting is to serve as a gathering point for meteorologists, forecasters, climatologists, atmospheric scientists, and atmospheric chemists where they can: (i) share their knowledge and consider progress at all levels, (ii) interact with peers and colleagues, (iii) debate scientific issues, and (iv) learn new things. PAPERS AND POSTERS The organisers invite contributions (either posters or talks) on topics including; the stratosphere, atmospheric chemistry, urban meteorology and air pollution, modeling (over all atmospheric scales of motion), hydrological applications, remote sensing, weather hazards, forecasting, data assimila- tion, agricultural and bio-meteorology, climate and impacts, including global change, seasonal fore- casting, and the history of New Zealand meteorology and atmospheric research. FORMAT Talks will be of 20 minutes duration including time for questions. Alternatively a poster presenta- tion, with a 5 minute oral description, may be requested. Audio-visual equipment will be available for all presentations. TITLES AND EXPRESSION OF INTEREST Those intending to present talks and/or posters are asked to submit the titles to Andrew Tait by email [email protected] by 31 August, 2011. Those planning to attend the conference but not give a talk are also requested to indicate their expression of interest by emailing Andrew by 31 August, ABSTRACTS Abstracts should not exceed one A4 page, and should include full address information as well as the corresponding author’s email address.

This is run under the auspices of the American Meteorological Society (AMS), in collaboration with the Institut de recherche pour le développement (IRD) and Météo-France . Since its advent, the ICSHMO has provided a unique contribution to ocean and atmosphere sci- ences that are specific to the Southern Hemisphere. The objective of the 2012 conference, the 10th of the series, is to provide an interdisciplinary forum for presentations of our current state of knowledge, as well as motivating new research and applications within the variety of disciplines related to weather and climate of the ocean and atmosphere. Met Soc Urban seminars: A talk was held on Wednesday, 4 May 2011 at NIWA Greta Point Wellington High Resolution modelling of air quality over London using the Unified Model Elizabeth Somervell (NIWA Christchurch) The forecasting model of the U.K. Meteorological Office (UKMO), known as the Unified Model (UM) has been developed to support a wide variety of global and mesoscale applications and increased resolution now allows the exploration of issues on smaller scales. Urban air quality is one such application that requires valid high resolution meteorological input and can bene- fit from a multi-scale approach. With this in mind, the UM has, for the first time, been coupled to the chemistry transport model CMAQ, in order to simulate a high pollution episode over the London area. Comparisons are made with ground based measurements for meteorological factors (temperature and wind speed) and air pollutant concentrations (ozone, NOx). A detailed analysis of the UM temperature and windspeed fields in relation to land use and diurnal cycle indicated improvements might be made to the UM surface scheme in order to better simulate meteorological processes that affect air quality in urban areas. A sensitivity analysis on the UM’s urban parametrisation was then undertaken. Of particular interest are the early hours of the morning, when the urban surface is under-going a critical cooling, and areas downwind of the urban centre. Biographical sketch: Elizabeth Somervell has recently joined the Air Quality and Health group at NIWA, after com- pleting her PhD at the University of Hertfordshire, UK. She has a broad background in envi- ronmental science and her previous work focused on urban meteorology using the Unified Model. Her current work falls under the Healthy Urban Atmospheres (HUA) programme and includes the investigation of drainage flows using mobile monitoring data. A talk was held on Thursday, 14 July 2011 at NIWA Greta Point Wellington Tracking Earth’s energy: From El Niño to global warming Speaker: Dr Kevin E. Trenberth, National Centre for Atmospheric Research, Boulder, CO 80307 The state of knowledge and outstanding issues with respect to the global mean energy budget of planet Earth was described, along with the ability to track changes over time. Best esti- mates of the main energy components involved in radiative transfer and energy flows through the climate system do not satisfy physical constraints for conservation of energy without ad- justments. The main issues relate to the downwelling longwave radiation and the hydrologi- cal cycle, and thus the surface evaporative cooling. It is argued that the discrepancy is 18% of the surface latent energy flux, but only 4% of the downwelling LW flux, and is most likely that the latter is seriously astray in some calculations, including many models. Beginning in 2000, the top-of-atmosphere radiation measurements provide stable estimates of the net global ra- diative imbalance changes over a decade, but after 2004 there is “missing energy” as the ob- serving system of the changes in ocean heat content, melting of land ice, and so on, is unable to account for where it has gone. Based upon a number of climate model experiments for the 21st century where there is a stasis in global surface temperature and upper ocean heat con- tent in spite of decade long periods with a known net energy input into the climate system, we infer that the main sink of the missing energy is likely the deep ocean below 275 m depth. Kevin also gave an interesting presentation to NZ Climate Change Institute at http:// www.victoria.ac.nz/climate-change/events/NZCCRI%20Seminar%20Series.aspx And from the Science Media Centre At http://www.sciencemediacentre.co.nz/2011/07/14/extreme-weather-and-climate-change/ Scientists participating in a briefing said more extreme weather can be expected in the years ahead as climate change plays a role in intensifying weather events.
