  1. Weekly work summary Yu Huizhen Jun. 22, 2013

  2. Plan of last week • Prepare for the qualify test. • Research survey.

  3. Brief summary of this week • Prepare for the qualify test. • Study the WRFDA.

  4. Research progress Study WRFDA Calculate the CNOP with low resolution.

  5. Papers • On the Predictability of SupercellThunderstorm Evolution • Main idea: on the condition that the model used is perfect, the study investigate the predictability of supercell thunderstorms. The conclusion is how the initial storm environment influence the supercell thunderstorm. From this paper, we can see that idealized study could make thing clearer and easier to study. • Mesoscale analyses and diagnostic parameters for deep convection nowcasting • Main idea: based on the ALADIN model and hourly routine observation, the paper study the relationship between the convection nowcasting and the CAPE and MOCON(moisture convergence). The results show that the thunderstorm triggering usually happens over areas of persistently high values of CAPE which ubdergo convergence continuously from four to one hour before the event.

  6. Paper • Improved nowcasting of precipitation based on convective analysis fields • Main idea: this paper talks about the ICNA system and its application. An approach to convective nowcasting is based on high-resolution analyses of some key convective diagnostics, such as CAPE, CIN, moisture convergence, and trigger temperature deficit. Case study results show that, on average the convection nowcast performs slightly better than the purely transitional nowcast on the areal precipitation nowcast. • Predictability of intense rain storms in the Central Mediterraneanbasin: sensitivity to upper-level forcing • Main idea: this study adopts a potential vorticity (PV) perspective to investigate the RAMS model quantitative precipitation forecast. The results show that the precipitation pattern is sensible to the upper-tropospheric forcing in terms of timing, abundance and pattern.

  7. Plan of next week • Qualify test • Group meeting • Analysis the CNOP, and try to add it to the initial state and simulate the case.
