The organisation was founded in late 18th century. In 1948, Romania ratified the 1947 Washington Convention, turning from a founding member to a full member of the World Meteorological Organization [1] (18 August 1948). [2] Since 2003, it is a member of EUMETSAT with a stake of 0.4456%. Today in Romania, ANM holds the monopoly for ...
The climate of Romania is continental, transitioning into humid subtropical (locally often "warm oceanic" or "Pontic") on the eastern coast, influenced by polar intrusions, and therefore characterized by harsh winters. The mountain ranges of the Carpathian arc have a cool mountain climate with high humidity throughout the year.
It comprises a spectral atmospheric model with a terrain-following vertical coordinate system coupled to a 4D-Var data assimilation system.In 1997 the IFS became the first operational forecasting system to use 4D-Var. [2] Both ECMWF and Météo-France use the IFS to make operational weather forecasts, but using a different configuration and resolution (the Météo-France configuration is ...
Approximately 16 km resolution with 70 vertical levels. [11] Covers the entire globe and 168 hours in the future twice a day, the shortest outlook of the synoptic scale models currently in use (most others run out at least 10 days; furthermore, the Unified Model forecasts are only available out 72 hours for non-paying users).
The Global Environmental Multiscale Model (GEM), often known as the CMC model in North America, is an integrated forecasting and data assimilation system developed in the Recherche en Prévision Numérique (RPN), Meteorological Research Branch (MRB), and the Canadian Meteorological Centre (CMC).
Weather reconnaissance aircraft, such as this WP-3D Orion, provide data that is then used in numerical weather forecasts.. The atmosphere is a fluid.As such, the idea of numerical weather prediction is to sample the state of the fluid at a given time and use the equations of fluid dynamics and thermodynamics to estimate the state of the fluid at some time in the future.
The middle and high-étage types are depicted above the sky cover circle of the station model, while the main low-étage cloud type is indicated below the circle. [5] Since the station model has limited room, it makes no special provision for vertical or multi-level clouds that can occupy more than one étage at a particular time. [13]
The MM5 (short for Fifth-Generation Penn State/NCAR Mesoscale Model) is a regional mesoscale model used for creating weather forecasts and climate projections. It is a community model maintained by Penn State University and the National Center for Atmospheric Research .
