El Niño and La Niña are counterparts in the El Niño-Southern Oscillation (ENSO), a cyclic warming and cooling of the eastern and central Pacific Ocean that exerts a major influence on global weather patterns, but they are not mirror images.
A detailed computer modeling study released today indicates that oil from the massive spill in the Gulf of Mexico might soon extend along thousands of miles of the Atlantic coast and open ocean as early as this summer.
Along with unusually persistent rains, there was a different kind of watery surprise this summer for people on the U.S. Atlantic coast. From the barrier islands of the Southeast to the rocky shores of Maine, tides ran as high as 2 feet above predicted values.
Melting of the Greenland ice sheet may drive more water than previously thought toward the already threatened coastlines of New York, Boston, Halifax, and other cities in the northeastern United States and Canada.
Andrea Sealy, NCAR's Advanced Study Program • If you are from the Caribbean and you're good at math and science, the advice you get is to become a doctor, says Sealy. "But I never liked biology much," she adds. Now she's a researcher at the Caribbean Institute for Meteorology and Hydrology.
NCAR scientists Bill Large and Steve Yeager have produced a new analysis of the exchanges of heat, momentum, and moisture between the oceans and atmosphere that should help climate modelers better assess variability on several time scales.
Joan Kleypas, NCAR's Climate and Global Dynamics Division • "Jacques Cousteau was my idol while growing up," confesses Kleypas. The undersea world revealed in his groundbreaking television programs inspired her to become an ocean scientist.
Holland recalls that when she entered graduate school at the University of Colorado, she had "the fuzzy idea of doing something with climate." She left graduate school with a sharp focus on the role of sea ice in the climate system.
