El Niño and African monsoon have strongly influenced intense hurricane frequency in the past

05-23-2007 · EurekAlert!

The frequency of intense hurricanes in the Atlantic Ocean appears to be closely connected to long-term trends in the El Niño/Southern Oscillation and the West African monsoon, according to new research from the Woods Hole Oceanographic Institution. Geologists Jeff Donnelly and Jonathan Woodruff made that discovery while assembling the longest-ever record of hurricane strikes in the Atlantic basin.

  2. Extended family ties influenced evacuation decisions during Hurricane Katrina
    04-27-2007 · EurekAlert!
    Previous research has shown that minorities have particularly cohesive extended family ties. For this study, researchers interviewed 58 randomly selected evacuees -- mostly low-income African Americans -- who relocated from New Orleans to Houston in the wake of Hurricane Katrina. The researchers found that the evacuees' strong family ties had a profound influence on factors affecting evacuation, including transportation decisions, access to shelter and how they perceived evacuation messages. These ties both facilitated and hindered their evacuation.

  3. European heat waves double in length since 1880
    08-03-2007 · EurekAlert!
    The most accurate measures of European daily temperatures ever indicate that the length of heat waves on the continent has doubled and the frequency of extremely hot days has nearly tripled in the past century. The new data shows that many previous assessments of daily summer temperature change underestimated heat wave events in western Europe by approximately 30 percent.

  5. Resistance and genetic sensitivity to sleeping sickness
    10-13-2006 · EurekAlert!
    Human African trypanosomiasis, transmitted by tse-tse fly bite, is a mainly rural disease and is strongly linked to people's living patterns and conditions, proximity to water-courses, in particular. Although environmental and behavioural risk factors are important in the epidemiology of human African trypanosomiasis, individual sensitivity to the disease appears to exist, according to experimental and immunological studies. IRD researchers investigated the role of human genetic diversity in the resistance or sensitivity to parasitic diseases, including sleeping sickness.

  6. Accuracy of past hurricane counts good
    11-26-2007 · EurekAlert!
    Counting tropical storms that occurred before the advent of aircraft and satellites relies on ships logs and hurricane landfalls, making many believe that the numbers of historic tropical storms in the Atlantic are seriously undercounted. However, a statistical model based on the climate factors that influence Atlantic tropical storm activity shows that the estimates currently used are only slightly below modeled numbers and indicate that the numbers of tropical storms in the recent past are increasing, according to researchers.

  9. Design the first map of active faults in the Gibraltar Arc to prevent earthquakes
    02-05-2008 · EurekAlert!
    Researchers from the University of Granada characterised the physical and mechanical properties of the Earth's crust of this area of intense seismic activity. The African and Eurasian plates get about 4 mm closer every year. The study related the temperature of the Earth's crust to its seismic activity, determining that the probability of earthquakes is significantly lower in areas of higher temperature. Results were published in the Journal of Geophysical Research and Tectonics.

  10. Wolves find happy hunting grounds in Yellowstone National Park
    08-30-2007 · EurekAlert!
    If Mark Boyce could converse with elk, he might give them a word of advice: avoid open, flat, snowy areas near rivers and roads. A biological scientist at the University of Alberta, Boyce analyzed 774 wolf-elk kill sites and concluded that spatial patterns of predation between wolves and elk are more strongly influenced by landscape features than by wolf distribution.
