Global climatic anomalies associated with extremes in the Southern Oscillation
Abstract Composite temperature and precipitation anomalies during various stages of an event in the Southern Oscillation (SO) have been computed for several hundred stations across the globe. Large
Threats to Water Supplies in the Tropical Andes
The climate models predict that greenhouse warming will cause temperatures to rise faster at higher than at lower altitudes, with potentially grave consequences for water supplies.
This paper provides an overview of climatic changes that have been observed during the past century at certain high-elevation sites, and changes in a more distant past documented by a variety of
Urbanization: Its Detection and Effect in the United States Climate Record
Abstract Several equations were developed that related the effect of urban growth, measured by increasing population, to the mean seasonal and annual temperature: the diurnal maximum, minimum,
North–South Precipitation Patterns in Western North America on Interannual-to-Decadal Timescales
The overall amount of precipitation deposited along the West Coast and western cordillera of North America from 258 to 558N varies from year to year, and superimposed on this domain-average
ENSO variability, teleconnections and climate change
An overview is presented of the principal features of the El Niño–Southern Oscillation (ENSO) teleconnections in terms of regional patterns of surface temperature, precipitation and mid‐tropospheric
Evidence for Intensification of North Pacific Winter Cyclones since 1948
Abstract Using NCEP–NCAR reanalysis and in situ data, evidence of important changes in the winter (December–March) cyclone climatology of the North Pacific Ocean over the past 50 years is found. The
Was there a ‘medieval warm period’, and if so, where and when?
It has frequently been suggested that the period encompassing the ninth to the fourteenth centuries A.D. experienced a climate warmer than that prevailing around the turn of the twentieth century.
Decadal Variability of Precipitation over Western North America
Abstract Decadal (>7- yr period) variations of precipitation over western North America account for 20%–50% of the variance of annual precipitation. Spatially, the decadal variability is broken into
