Ancient Maya Cities

October 6, 1929
And above all things we wished to get an idea
of what the Maya country really looks like, for
in spite of the fact that archeologists have for
many years been pushing their way into that
region, they have been so buried in the welter of
forest, their outlook has been so stifled by mere
weight of vegetation, that it has been impossible
to gain a comprehensive understanding of the real
nature of this territory, once occupied by
Americas most brilliant native
civilization. Dr. A.V. Kidder, Carnegie
Institution (Member of Col. Charles A.
Lindberghs exploratory overflight of the Maya
region)

Hurricane Preparedness
  • Using QuikScat data, forecasters can now predict
    hazardous weather events over the oceans as much
    as 12 hours earlier.
  • Researchers are developing methods that can
    detect potential tropical cyclones more than 40
    hours earlier than with traditional methods.
  • TRMM is providing 3 dimensional maps of
    precipitation structure

Mesoamerican Deforestation Scenarios
Implications for Wet and Dry Seasons (MM5)
January (dry season) Temperature (left) warms
everywhere but only by 1-2deg C Rainfall (right)
- little impact as its the dry season!
July (wet season) Temperature (left) warms
everywhere, but now as much as 2-5 deg
C. Rainfall (right) shows a decrease of
20-30 over much of the Mayan region

CCSM3
This plot shows rainfall over the Maya lowland
region for the wet season (June-September) for
100 years of present-day conditions as
simulated by a global climate model. Many
periods of 3-4 successive dry years can be seen,
but few prolonged droughts.
This plot shows rainfall for the wet season for a
model simulation of the period 1870-1999. Note
much more prolonged periods of drought, e.g.,
1952-1981, during which 24 of 30 years have
below average rain.
