In the decade before THORPEX, detailed diagnostic case studies using aircraft measurements [e.g., Experiment on Rapidly Intensifying Cyclones over the Atlantic (ERICA; Hadlock and Kreitzberg 1988) and FASTEX] had already shown that diabatic processes, in particular diabatic heating and cooling, can impact the large-scale dynamics via PV modification (Neiman et al.
As one of the primary international scientific projects, THORPEX aims to contribute to our society, economics, and environment by advancing a unified observation-forecast system and improving the accuracy of 1-14 days' high impact weather forecast.
*** THORPEX was a 10-yr international research program designed to accelerate the rate of improvement in the accuracy of predictions of high-impact weather.
A main deliverable of this project is the establishment of an extensive database containing subseasonal (up to 60 days) forecasts, 3 weeks behind real time, and reforecasts from 11 operational centers, modeled in part on the The Observing System Research and Predictability Experiment (THORPEX) Interactive Grand Global Ensemble (TIGGE) database for medium-range forecasts (up to 15 days).
In particular, the concept of "targeting" observations in selected regions to improve a forecast of a high-impact weather event had been promoted and tested prior to and during the World Meteorological Organization/World Weather Research Programme's The Observing System Research and Predictability Experiment (THORPEX) era (2005-14), through field campaigns and assimilation experiments.
A survey of the global forecasting systems used for short-range and medium-range predictions, such as the ones that contribute to The Observing System Research and Predictability Experiment (THORPEX) Interactive Grand Global Ensemble (TIGGE; Bougeault et al.
This is one of the major benefits of the grand ensemble of models formulated for THORPEX by The TIGGE Project (see Richard Swinbank and colleagues' article on p.
The International Grand Global Ensemble (TIGGE) was a major component of The Observing System Research and Predictability Experiment (THORPEX) research program, whose aim is to accelerate improvements in forecasting high-impact weather.
For example, the typhoon-track forecast error in four numerical weather prediction models was reduced by 20%-40% consistently as a result of dropsonde data collected during The Observing System Research and Predictability Experiment (THORPEX) Pacific Asian Regional Campaign (T-PARC) in 2008 (Weissmann et al.
The flex mode is one example of the "targeted observations" concept, outlined during The Observing System Research and Predictability Experiment (THORPEX; Shapiro and Thorpe 2004).
