Temperature anomalies for June 2005 are shown on the two maps
below. The dot map on the left uses anomalies that were calculated
from the Global Historical Climatology Network (GHCN) data set of
land surface stations using a 1961-1990 base period. The map on the
right is a weekly product based on data from the Comprehensive
Ocean-Atmosphere Data Set (COADS) of SST data. During June, there
were above average temperatures over much of the eastern half of
the U.S., Alaska, Canada, southern Brazil, western Europe, eastern
Australia, southeastern Asia, India, Siberia and Japan. Cooler than
average temperatures were observed over the U.S. Rocky Mountains,
eastern Australia, Afghanistan, Pakistan, parts of the Caribbean
and Scandinavia. |

| Above average SSTs are
evident in the product above. Much warmer than average anomalies
occurred over the northern Atlantic, the northern Pacific,
particularly off the coast of Alaska as well as the over the
Mediterranean Sea. Slightly warmer than average temperatures were
observed over the eastern and central Pacific, indicating a
continuation of neutral ENSO conditions. Cooler than average SSTs
were observed off the coasts of Ecuador and Peru and the western
tropical coast of Africa. The mean position of upper level ridges of high pressure and troughs of low pressure (depicted by positive and negative 500 millibar height anomalies on the June 2005 map) are generally reflected by areas of positive and negative temperature anomalies at the surface, respectively.

The maps below represent anomaly values based on the GHCN data set
of land surface stations using a base period of 1961-1990. During
June 2005, above average precipitation fell over the U.S. northern
Great Plains, the southeastern U.S., the Caribbean, Colombia,
southern Chile and Argentina, southeastern Asia and the majority of
Australia. Below average precipitation was observed over the U.S.
southern Great Plains, northern Mexico, much of Europe, India and
Japan. |
