Low-Level-Jet and Inversion statistics for Weddell Sea region of Antarctica
This data set is a climatology (2002–2016) of low level jet (LLJ) and inversion parameters for the Weddell Sea region of Antarctica. Mean (Summer=April-Sept., Winter=Dez.-Jan., Annual) values were computed from hourly COSMO-CLM model output. To detect a LLJ the lowest 1 km of the atmosphere was sear...
