Important features for soil development and correlation include:<\/p>\n<ul>\n<li>Warm temperatures, with an annual mean of about 27\u00ba C, and an annual range of monthly means of less than 2\u00ba C; and diurnal ranges of about 8 &#8211; 10\u00ba C.<\/li>\n<li>Mean annual rainfall of about 2600 mm, with a strongly seasonal distribution. Monthly rainfall averages less than 60 mm for the January \u2013 April dry season. Individual dry seasons vary in severity, and range in length from three to five months. The May &#8211; December wet season precipitation and annual totals also vary. Consequently the amount of water surplus to evapotranspiration and soil recharge needs and therefore available for overland flow, erosion, solute leaching, hydrolytic weathering, and catenary redistribution of solutes and colloids is temporally, as well as spatially, variable, ranging from zero up to about 1500 mm p.a.<\/li>\n<li>The rainfall can attain potentially erosive intensities of up to 100 mm hr<sup>-1<\/sup> for short periods.<\/li>\n<li>There are strong gusts of wind that can uproot trees (Foster &amp; Brokaw, 1996), especially in the west of the island. However, BCI lies to the south of the main hurricane tracks.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Location and access BCI is in the Gatun Lake, at the northwestern (Caribbean) end of the Panama Canal, in the central part of the Republic of Panama, Central &hellip; <a href=\"https:\/\/striresearch.si.edu\/bci-soil-map\/content\/bci-survey-area\/\"><\/a><\/p>\n","protected":false},"author":2,"featured_media":162,"parent":7,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"inline_featured_image":false,"_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","_exactmetrics_skip_tracking":false,"footnotes":""},"class_list":["post-56","page","type-page","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 -
