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

<p>These&nbsp;.mat files contain&nbsp;the dates of blocking days over two&nbsp;domains around the Antarctic Peninsula: a domain located to the west (150-90&ordm;W, 50-70&ordm;W) and a domain located over and to the east of the Peninsula (90-30&ordm;W, 50-70&ordm;W). Extreme blocking&nbsp;on each domain occurs when the mean&nbsp;500 hPa geopotential height, averaged over the domain, is larger than the 90% percentile. Very extreme blocking occurs when the mean&nbsp;500 hPa geopotential height, averaged over the domain, is larger than the 95% and 99% percentiles.</p> <p>Variables included within each file:</p> <p>- date_500mb_p90</p> <p>-&nbsp;date_500mb_p95</p> <p>- date_500mb_p99</p> <p>They represent the dates of extreme and very extreme blocking on each domain</p> <p>-&nbsp;geo_h500mb_p90</p> <p>-&nbsp;geo_h500mb_p95</p> <p>-&nbsp;geo_h500mb_p99</p> <p>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.</p> <p>Also included on each file are variables:</p> <p>-&nbsp;date_500mb_p90_sor</p> <p>-&nbsp;date_500mb_p95_sor</p> <p>-&nbsp;date_500mb_p99_sor</p> <p>which are just the dates of extreme and very extreme blocking days sorted in ascending order.</p> <p>For more details on this dataset, see&nbsp;</p> <p><strong>J.
