The THORPEX Pacific Asian Regional Campaign (T-PARC) is a multi-national field campaign planned by the Asian and North American Regional Committees and their associated national science committees that address the shorter-range dynamics and forecast skill of one region (Eastern Asian and the western North Pacific) and its impact on the medium-range dynamics and forecast skill of downstream regions (eastern North Pacific, North America and perhaps stretching to Europe). The field phase of T-PARC was designed to leverage multi-national efforts to address these two overarching foci. While T-PARC encompasses varying time and space scales, the primary objectives of each region are the same (i.e., to increase understanding of the mechanisms that will lead to improved predictive skill of high impact weather events). T-PARC was carried out in May to December 2008 with a concentrated US measurement campaign during August and September of that year.
