100 years ago to the day, the grandiose R.M.S. Titanic passed honorably beneath the icy waters of the North Atlantic. You may be asking yourself what does weather have to do with the Titanic? Well, besides my personal fascination with the event, the answer is quite a lot actually. Based on historic ship weather records and investigative accounts for April 14-15, 1912, it is believed that the night's seemingly fair conditions--clear skies, cold temperatures, variable winds, and light fog--were a catalyst for the ship's demise. Had Arctic high pressure not created a placid, glassy ocean surface and a still black-lit horizon, visual signs of surrounding icebergs may have been easier to spot at a greater distance.
