Project management plan activities

.

(WP1) Sodar data reprocessing, obtaining of statistical analyzes of wind profiles and turbulence parameters data for annual, seasonal and monthly periods.

  • uniform treatment of the sodar raw data observations – this task is required, as the acoustic remote sensing system allows different regimes of sounding and data derivation (depending on the goals and types of research) and during different periods different acquisition protocols have been used. The storage of all raw data allows later different treatment. For this reason, onetime uniform treatment of the sodar raw data (including uniform output parameters tuning, choice of output parameters, uniform quality control (QC) of the data, uniform temporal resolution and averaging time, uniform method of data acquisition) will be performed;
  • import the new data from reprocessing in a format suitable for working in the MatLab environment and create a database of acoustic sounding of the coastal ABL suitable; for future project actions;
  • preparation of annual, seasonal, and monthly statistical analyzes for wind profiles and turbulence parameters at each level of the sodar measurements;

.

(WP2) Analysis of coastal events with representative meteorological conditions for the study region over the entire research period and selection of appropriate periods for events modeling.

  • precision overview of the created database of acoustic sounding of the coastal ABL over the entire research period;
  • tagging only of coastal events with sufficient data availability in time and space with representative meteorological conditions;
  • classification of certain representative costal evens related to local circulation (breeze), calm weather, wind flow from a different direction, and various coastal phenomena as sharp changes in the field of wind, local frontal systems, kernel in the wind speed field in the breeze sell, low-level jet and etc;
  • selection of appropriate periods from different types of reprehensive coastal events with sufficient duration for mesometeorological modeling;

.

(WP3) Modelling of the wind field with WRF numerical mesometeorological simulations and interpolation of output to the levels of measurements (values at every 10 m height) to derive correlation relationships with actual sodar measurements.

  • configuration of the WRF model: selecting the parameterization of the physical processes that will be used for the numerical simulations in EP Ahtopol, adoption of several nested domains; 
  • initialization of WRF model simulations for the selected extreme events periods with high temporal resolution (10 minutes) and an optimal number of vertical levels in the first 1000 meters above the surface;
  • review of the model results and calculation of interpolated model data to multiple sub-level between the actual simulation heights by the linear approximation of the model data in order to get as close to the levels of sodar measurements;

.

(WP4) Analysis of correlation coefficients between interpolated model data and sodar measurements in chosen coastal events with sufficient data availability.

  • obtaining correlation coefficients between five pairs of variables (model data/measurements) – wind direction and speed (WD, WS), and three wind vector components (W – vertical velocity, U – Eastern component, and V – north component):

– time-series comparison at a certain height;

– individual profiles comparison at a given time;

.

(WP 5) Project management actions to ensure successful implementation of the project, to facilitate the achievement of the goals set and to disseminate the results.

  • individual work packages activities interaction and coordination, deadlines implementation;
  • coordination and monitoring of the project stages reports preparation;
  • comprehensive results review and selection of the appropriate ones for presentation in scientific publications and conferences;
  • stimulating the postdoctoral fellow to deep and improve his knowledge and professional skills with searching of applicable WRF training courses, workshops, seminars, and project results presenting opportunities at national and international conferences;
  • project research results preparation for scientific publications;
  • promote the objectives and tasks of the project on the Internet through the preparation of a webpage where, besides general information on the project, the achieved results of the set tasks to be announced;
