  • Multimodel probabilistic prediction of 2 m-temperature anomalies on
           the monthly timescale

    • Abstract: Multimodel probabilistic prediction of 2 m-temperature anomalies on the monthly timescale
      Alfonso Ferrone, Daniele Mastrangelo, and Piero Malguzzi
      Adv. Sci. Res., 14, 123-129, doi:10.5194/asr-14-123-2017, 2017
      The ensemble reforecasts of the CNR-ISAC and ECMWF forecasting systems, both participating to the S2S project, have been combined in a multimodel ensemble. Tercile probability predictions of wintertime 2 m temperature produced through logistic regression outperform the probability estimation based on the direct count of ensemble members, in terms of RPSS and reliability diagrams. Also, it is argued that the logistic regression would not yield further improvements if a larger dataset were used.

    • Abstract: Subseasonal-to-seasonal (S2S) forecasts with CNRM-CM: a case study on the July 2015 West-European heat wave
      Constantin Ardilouze, Lauriane Batté, and Michel Déqué
      Adv. Sci. Res., 14, 115-121, doi:10.5194/asr-14-115-2017, 2017
      Was the July 2015 heat wave that struck Western Europe predictable more than 10 days ahead and to what extent? This article addresses the question by assessing forecasts from the CNRM-CM sub-seasonal forecast system. It is found that a warm anomaly was anticipated up to one month ahead despite the limited skill of the forecast system at such lead-time. The possible causes for this relative success are then discussed.

      Adv. Sci. Res., 14, 103-107, doi:10.5194/asr-14-103-2017, 2017
      Exact description of cloud microphysical processes is essential for providing accurate weather forecasts. The paper evaluates errors of different methods to account for variability of cloud microphysical parameters, such as cloud water. rain water, and cloud drop concentration. It is found that neglecting cloud variability results in a substantial underestimate of rain development in the short run. Nevertheless the total effect on rain development in the long run may be uncertain due to the fac

  • Ensemble using different Planetary Boundary Layer schemes in WRF model for
           wind speed and direction prediction over Apulia region

    • Abstract: Ensemble using different Planetary Boundary Layer schemes in WRF model for wind speed and direction prediction over Apulia region
      Andrea Tateo, Mario Marcello Miglietta, Francesca Fedele, Micaela Menegotto, Alfonso Monaco, and Roberto Bellotti
      Adv. Sci. Res., 14, 95-102, doi:10.5194/asr-14-95-2017, 2017
      The Weather Research and Forecasting mesoscale model(WRF) was used to simulate hourly 10 m wind speed and direction over the cityof Taranto, Apulia region (south-eastern Italy). This area is characterizedby a large industrial complex including the largest European steel plant andis subject to a Regional Air Quality Recovery Plan. This plan constrainsindustries in the area to reduce by 10 % the mean daily emissionsby diffuse and point sources during specific meteorological conditions namedwind days. According to the Recovery Plan, the Regional Environmental AgencyARPA-PUGLIA is responsible for forecasting these specific meteorologicalconditions with 72 h in advance and possibly issue the earlywarning.
      In particular, an accurate wind simulation is required. Unfortunately,numerical weather prediction models suffer from errors, especially for whatconcerns near-surface fields. These errors depend primarily on uncertaintiesin the initial and boundary conditions provided by global models andsecondly on the model formulation, in particular the physicalparametrizations used to represent processes such as turbulence, radiationexchange, cumulus and microphysics. In our work, we tried to compensate forthe latter limitation by using different Planetary Boundary Layer (PBL)parameterization schemes. Five combinations of PBL and Surface Layer (SL)schemes were considered.
      Simulations are implemented in a real-time configuration since our intentionis to analyze the same configuration implemented by ARPA-PUGLIA foroperational runs; the validation is focused over a time range extending from49 to 72 h with hourly time resolution. The assessment of theperformance was computed by comparing the WRF model output with ground datameasured at a weather monitoring station in Taranto, near the steel plant.After the analysis of the simulations performed with different PBL schemes,both simple (e.g. average) and more complex post-processing methods (e.g.weighted average, linear and nonlinear regression, and artificial neuralnetwork) are adopted to improve the performances with respect to the outputof each single setup. The neural network approach comes out as the mostpromising method.

      Adv. Sci. Res., 14, 89-93, doi:10.5194/asr-14-89-2017, 2017
      Finnish Meteorological Institute and Helen Ltd examined the feasibility of long-range forecasts (longer than two weeks) of temperature for needs of the energy sector in Helsinki, Finland. In this study, we examined the quality of Heating degree day (HDD) forecasts. As the forecasts we used UK Met Office seasonal forecasts. The long-range forecasts of monthly HDD showed some skill in Helsinki in winter 2015–2016, up to two months, especially if the very cold January is excluded.

      Adv. Sci. Res., 14, 85-88, doi:10.5194/asr-14-85-2017, 2017
      The probabilistic evaluation of 2 m temperature forecast of about one year of monthly ensemble forecasts, issued on a monthly basis, is provided. The ranked probability skill score, averaged over all the available cases, shows that the system has a residual predictive skill beyond week 2 on some peculiar regions. Reliability diagrams show that, in general, the probability forecasts of above-normal observed temperature are more reliable than below-normal temperature.

    • Abstract: Sensitivity of sea-level forecasting to the horizontal resolution and sea surface forcing for different configurations of an oceanographic model of the Adriatic Sea
      Lidia Bressan, Andrea Valentini, Tiziana Paccagnella, Andrea Montani, Chiara Marsigli, and Maria Stefania Tesini
      Adv. Sci. Res., 14, 77-84, doi:10.5194/asr-14-77-2017, 2017
      This study presents the sensitivity of an oceanic model of the Adriatic Sea to the horizontal resolution and to the meteorological forcing. The model is run with two different configurations and with two horizontal grids at 1 and 2 km resolution. To study the influence of the meteorological forcing, the two storms have been reproduced by running ROMS in ensemble mode. Possible optimizations of the model set-up are deduced by the comparison of the different run outputs.

      Adv. Sci. Res., 14, 71-75, doi:10.5194/asr-14-71-2017, 2017
      Monthly frequencies of circulation types (derived by clustering fields of SLP, vertical wind and rel. humidity at 700 hPa and regional rainfall series) are used as predictors in regression models for monthly frequencies of regional precipitation extremes (> 95 % percentile). With predictor output from global climate models, changes in regional precipitation extremes for 2021–2050 and 2071–2100 are assessed, most distinctive in summer: increasing/decreasing extremes for the earlier/later period.

      Adv. Sci. Res., 14, 35-48, doi:10.5194/asr-14-35-2017, 2017
      This study investigates the characteristic time-scales of variability found in long-term time-series of daily means of surface solar irradiance (SSI). Estimates of SSI from satellite-derived HelioClim-3 and radiation products from ERA-Interim and MERRA-2 re-analyses are compared to WRDC measurements. It is found that HelioClim-3 renders a more accurate picture of the variability found in ground measurements, not only globally, but also with respect to individual characteristic time-scales.

Theinverse process, i.e. the conversion from tilted to horizontal isinvestigated here based upon seven months of in-plane global solar irradiancemeasurements recorded on the roof of the Royal Meteorological Institute ofBelgium's radiation tower in Uccle (Longitude 4.35° E, Latitude50.79° N). Up to three pyranometers mounted on inclined planes ofdifferent tilts and orientations were involved in the inverse transpositionprocess. Our results indicate that (1) the tilt to horizontal irradianceconversion is improved when measurements from more than one tiltedpyranometer are considered (i.e. by using a multi-pyranometer approach) and(2) the improvement from using an isotropic model to anisotropic models inthe inverse transposition problem is not significant.

      The solar hourly irradiation received at ground level estimated by the databases HelioClim-3v4, HelioClim-3v5 and Copernicus Atmosphere Monitoring Service (CAMS) Radiation Service are compared to measurements made in stations in Oman and Abu Dhabi. The correlation coefficients are greater than 0.97. The relative bias is less than 5%. Each database captures accurately the temporal and spatial variability of the irradiance field. The three databases are reliable sources to assess solar radiation.

      Determination of heat requirements in the first developing phases of plants has been expressed as Growing Degree Days (GDD) and is useful in order to understand the flowering season development in plant species, and forecast when flowering will occur. The study dealt with the estimation of GDD in Crete Island in Greece. Results indicated that in the future, GDD will be increased and the existing cultivations can reach maturity sooner. Neverthelless, rough topography will act as an inhibitor.

  • Climate reference stations in Germany:
           Status, parallel measurements and
           homogeneity of temperature time series

    • Abstract: Climate reference stations in Germany: Status, parallel measurements and homogeneity of temperature time series
      Frank Kaspar, Lisa Hannak, and Klaus-Jürgen Schreiber
      Adv. Sci. Res., 13, 163-171, doi:10.5194/asr-13-163-2016, 2016
      Germany's national meteorological service (DWD) operates a network of so-called climate reference stations. At these stations parallel measurements are performed in order to allow the comparison of manual and automatic observations. We present an analysis of parallel measurements of temperature at 2 m height. It is shown that the automation of stations did not cause an artificial increase in the series of daily mean temperature. A bias occurs for maximum temperature in specific configurations.

  • Wind speed variability between 10 and 116 m height from the regional
           reanalysis COSMO-REA6 compared to wind mast measurements over Northern
           Germany and the Netherlands

    • Abstract: Wind speed variability between 10 and 116 m height from the regional reanalysis COSMO-REA6 compared to wind mast measurements over Northern Germany and the Netherlands
      Michael Borsche, Andrea K. Kaiser-Weiss, and Frank Kaspar
      Adv. Sci. Res., 13, 151-161, doi:10.5194/asr-13-151-2016, 2016
      Wind speeds derived from the regional reanalysis COSMO-REA6 and from two global reanalyses of ECMWF (ERA-Interim and ERA-20C) have been compared to tower measurements covering heights from 10 m up to 140 m, located in the North Sea, in The Netherlands, and in Northeast Germany. In general, the monthly and hourly mean values of COSMO-REA6 are at least as close to the measurements as the global reanalyses, and in the correlation of daily means an added value of COSMO-REA6 is found.

  • An overview of the use of Facebook in National Weather Services

    • Abstract: An overview of the use of Facebook in National Weather Services
      Virginia Palacio, Olatz Principe, Maialen Martija, and Santiago Gaztelumendi
      Adv. Sci. Res., 13, 145-150, doi:10.5194/asr-13-145-2016, 2016
      Facebook is one of the most used social networks and it represents a perfect virtual platform to share information and to promote active and immediate interaction amongst users. This is why many NMSs develop new communication strategies and incorporate this tool for different purposes. In this paper we investigate how Facebook was introduced in different NMSs worldwide as an additional tool for the diffusion of meteorological information and interction with users.

  • Study of NWP parameterizations on extreme precipitation events over Basque
           Country

    • Abstract: Study of NWP parameterizations on extreme precipitation events over Basque Country
      Iván R. Gelpi, Santiago Gaztelumendi, Sheila Carreño, Roberto Hernández, and Joseba Egaña
      Adv. Sci. Res., 13, 137-144, doi:10.5194/asr-13-137-2016, 2016
      The Weather Research and Forecasting model (WRF), like other numericalmodels, can make use of several parameterization schemes. The purpose of thisstudy is to determine how available cumulus parameterization (CP) andmicrophysics (MP) schemes in the WRF model simulate extreme precipitationevents in the Basque Country. Possible combinations among two CP schemes(Kain–Fritsch and Betts–Miller–Janjic) and five MP (WSM3, Lin, WSM6, newThompson and WDM6) schemes were tested. A set of simulations, correspondingto 21st century extreme precipitation events that have caused significantflood episodes have been compared with point observational data coming fromthe Basque Country Automatic Weather Station Mesonetwork.
      Configurations with Kain–Fritsch CP scheme produce better quantity ofprecipitation forecast (QPF) than BMJ scheme configurations. Depending onthe severity level and the river basin analysed different MP schemes showthe best behaviours, demonstrating that there is not a unique configurationthat solve exactly all the studied events.
