RA VI Operating Plan 2012-2015
Following the advice of the XV Session of the Association, the TT-SPAP developed the regional Operating Plan by compiling the tasks in the Work Programmes of the Working Groups. Thus, the Operating Plan contains concrete tasks and deliverables aimed at assisting RA VI Members to implement their national plans for further development of their NMHSs and improvement of the provision of meteorological, hydrological and climatological services for supporting their national economies and the society. The RA VI Operating Plan is intended to be a living document regularly monitored and adjusted as nec ...

The recent shift in early summer Arctic atmospheric circulation: in Geophysical Research Letters, vol. 39, L19804
The last six years (2007–2012) show a persistent change in early summer Arctic wind patterns relative to previous decades. The persistent pattern, which has been previously recognized as the Arctic Dipole (AD), is characterized by relatively low sea-level pressure over the Siberian Arctic with high pressure over the Beaufort Sea, extending across northern North America and over Greenland. Pressure differences peak in June. In a search for a proximate cause for the newly persistent AD pattern, we note that the composite 700 hPa geopotential height field during June 2007–2012 exhibits a positive ...
GSICS Executive Panel, eleventh session: final report
WMO, 2012The eleventh session of the GSICS Executive Panel (EP) was hosted by ROSHYDROMET in St Petersburg on 2 October 2011 in conjunction with the 39th session of CGMS. The Panel noted the good progress made by both the GSICS Data Management Working Group (GDWG) and the GSICS Research Working Group (GRWG). It stressed the importance and the benefit of following a harmonized methodology throughout the agencies and encouraged IMD and ISRO to resume contact with the GSICS Coordimation Centre (GCC) with a view to facilitate implementation of GSICS corrections on INSAT and Kalpana. The Panel invited the ...
International organizing committee for the WMO solid precipitation intercomparison experiment, second session : final report
This report provides a summary of the second session of the International Organizing Committee (IOC) of the WMO Solid Precipitation Intercomparison Experiment (SPICE) that was held in Boulder, USA, from 11 to 15 June 2012. The IOC reviewed the outcomes of the informal Pre-SPICE experiment that took place during the winter of 2011/12 in the interest of assessing the principles of the formal intercomparison and to address, in particular, the configuration of a working field reference using an automatic gauge. The IOC reviewed a number of aspects dealing with the configuration and operatio ...
PWS, 25. Guidelines on Participation of National Meteorological and Hydrological Services in the WMO World Weather Information Service
This guide is targeted at NMHSs and is intended to demonstrate the benefits that NMHSs gain by participating in WWIS, and to provide step-by-step guidance for a National Meteorological or Hydrometeorological Service (NMS) wishing to either join the WWIS initiative or to enhance its level of participation. Templates of the standard forms that NMHSs would need to complete to join or enhance participation in the WWIS are also provided.
Verification of mobile weather alert forecasts over Lake Victoria in Uganda
Several studies suggest that weather patterns over Lake Victoria are highly variable, with wind gusts in the vicinity of thunderstorms suddenly thrashing up high waves capable of capsizing small fishing boats. In order to improve safety on the lake, the Mobile Weather Alert (MWA) service is implemented by utilising mobile phone technology to provide daily weather forecasts that reduces vulnerability of fishermen to weather hazards. This service was developed as a pilot scheme under the WMO Severe Weather Forecast Demonstration Project (SWFDP). An evaluation of MWA forecasts over Lake Victoria ...
Guidelines on Ensemble Prediction Systems and Forecasting
Ensemble Prediction Systems (EPS) are numerical weather prediction (NWP) systems that allow us to estimate the uncertainty in a weather forecast as well as the most likely outcome. Instead of running the NWP model once (a deterministic forecast), the model is run many times from very slightly different initial conditions. Often the model physics is also slightly perturbed, and some ensembles use more than one model within the ensemble (multi-model EPS) or the same model but with different combinations of physical parameterization schemes (multi-physics EPS). Owing to the cost of running ...

Workshop on Aircraft Observing System Data Management: final report
The Workshop on Aircraft Observing System Data Management was hosted by the WMO Secretariat, over 5-8 June, 2012, in Geneva, Switzerland. The Workshop was a joint initiative of the WMO AMDAR Panel and the CBS Expert Team on Aircraft-based Observations (ET-AIR). The aims and objectives, which are provided in full within Appendix II, were chiefly concerned with furthering two tasks within the WIGOS Pilot Project for AMDAR, namely the “Development of a standardised Quality Management Framework for AMDAR data”, and, the “Application of WMO Metadata relevant to AMDAR”. The Workshop also covered a n ...

The Strategy incorporates assessment of user needs and the application of performance metrics.
WWRP, 2012-1. Recommended Methods for Evaluating Cloud and Related Parameters
World Meteorological Organization (WMO) ; WWRP/WGNE Joint Working Group on Forecast Verification Research (JWGFVR) - WMO, 2012Cloud errors can have wide-reaching impacts on the accuracy and quality of outcomes, most notably, but not exclusively, on temperature. This is especially true for weather forecasting, where cloud cover has a significant impact on human comfort and wellbeing. Whilst public perception may not be interested in absolute precision, i.e. whether there were 3 or 5 okta of cloud, there is anecdotal evidence to suggest strong links between the perceptions of overall forecast accuracy and whether the cloud was forecast correctly, mostly because temperature errors often go hand-in-hand. It is therefore ...
CGMS Baseline for the operational contribution to the GOS (adopted by CGMS-39 on 6 October 2011: Future satellite missions to be performed on operational/sustained basis
In support of the programmes coordinated or co-sponsored by WMO for weather and climate, CGMS Members plan to maintain the operational capabilities and services described below, that constitute the “CGMS baseline for the operational contribution to the GOS”. While this particular document focuses on missions that are decided and managed in an
operational or sustained framework, with a perspective of long-term follow-on, this in no way precludes the importance of other missions undertaken e.g. on a research or demonstration basis. First of all, because today’s research and development a ...
WMO Statement on the status of the global climate in 2011
The World Meteorological Organization’s Annual Statement on the Status of the Global Climate said that 2011 was the 11th warmest since records began in 1850. It confirmed preliminary findings that 2011 was the warmest year on record with a La Niña, which has a cooling influence. Globally-averaged temperatures in 2011 were estimated to be 0.40°C above the 1961-1990 annual average of 14°C.

Руководящие указания по системам ансамблевого прогнозирования и прогнозированию
Системы ансамблевого прогнозирования (САП) представляют собой системы численного прогнозирования погоды (ЧПП), которые позволяют нам оценивать неопределенность в прогнозе погоды, а также наиболее вероятный исход. Вместо прогона модели ЧПП один раз (детерминированный прогноз) модель прогоняется много раз с несколько разными исходными условиями. Во многих случаях физика модели бывает также несколько возмущенной, а некоторые ансамбли используют более одной модели внутри ансамбля (мультимодельная САП) или одну и ту же модель, но с различными комбинациями схем физической параметризации (мул ...
Directrices sobre los sistemas de predicción por conjuntos y la predicción
Los sistemas de predicción por conjuntos son sistemas de predicción numérica del tiempo (PNT) que permiten estimar la incertidumbre de una predicción meteorológica, así como el desenlace más probable del proceso predicho. En lugar de ejecutar el modelo de PNT una sola vez (predicción determinística), se ejecuta numerosas veces partiendo de condiciones iniciales ligeramente diferentes. Con frecuencia se introduce también una ligera perturbación en los parámetros físicos del modelo, y algunos conjuntos hacen uso de más de un modelo (sistema de predicción por conjuntos multimodelo), o bien ...
