Dates and 500 hPa geopotential height of P90, P95 and P99 blocking days

These .mat files contain the dates of blocking days over two domains around the Antarctic Peninsula: a domain located to the west (150-90ºW, 50-70ºW) and a domain located over and to the east of the Peninsula (90-30ºW, 50-70ºW). Extreme blocking on each domain occurs when the mean 500 hPa geopotential height, averaged over the domain, is larger than the 90% percentile. Very extreme blocking occurs when the mean 500 hPa geopotential height, averaged over the domain, is larger than the 95% and 99% percentiles. Variables included within each file: - date_500mb_p90 - date_500mb_p95 - date_500mb_p99 They represent the dates of extreme and very extreme blocking on each domain - geo_h500mb_p90 - geo_h500mb_p95 - geo_h500mb_p99 They represent the corresponding 500 hPa mean geopotential height averaged over each domain during extreme (values larger than 90% percentile) and very extreme (values larger than the 95% and 99% percentiles) blocking days. Also included on each file are variables: - date_500mb_p90_sor - date_500mb_p95_sor - date_500mb_p99_sor which are just the dates of extreme and very extreme blocking days sorted in ascending order.
