| Abstract: | A polar low (PL) which occurred in October 1993 over the Norwegian Sea is investigated from an
observational and a numerical point of view. This PL has several unique features: it developed early in the season,
it lasted for about 3 days, and its trajectory was such that it passed over weather stations so that ‘conventional’ observations of the low are available. The conditions of the formation, development and decay of the PL are
investigated using a double approach: satellite data from several instruments are used together to document the mesoscale structure of the low, and two versions of a limited-area model are run to investigate the dynamics of the low. Numerical model fields are compared to quantities derived from TIROS-N Operational Vertical Sounder, the Special Sensor Microwave/Imager, and satellite radar altimeter data. In spite of a better spatial resolution of the models, humidity and surface wind speeds are less organized in the simulations than in satellite retrievals.... |
