Precipitation totals 20126/13/2023 ![]() ![]() NCDC will not update the static reports from October through December 2012 and the 2012 U.S and Global annual reports, but will use the current dataset (GHCN-M v. More complete information about this issue is available at this supplemental page. For the globe, ranks of individual years changed in some instances by a few positions, but global temperature trends changed no more than 0.01☌/century for any month since 1880. winter temperature are higher while trends in summer temperatures are lower. ![]() This effect is related to the seasonal nature of the reintroduced time-of-observation correction. stations and neighboring stations in Canada and Mexico.Ĭompared to analyses released in January 2013, the trend for certain calendar months has changed more than others. The version 3.2.1 release also includes the use of updated data to improve quality control and correction processes of other U.S. It successfully corrected for many of the time of observation issues, which minimized the effect of this processing omission. algorithm that addresses such issues, but in an indirect manner. That algorithm provides for a physically based correction for observing time changes based on station history information. The first correction for time of observation changes in the United States was inadvertently disabled during late 2012. NCDC uses two correction processes to remove inhomogeneities associated with factors unrelated to climate such as changes in observer practices, instrumentation, and changes in station location and environment that have occurred through time. For the globe, ranks of individual years changed in some instances by a few positions, but global land temperature trends changed no more than 0.01☌/century for any month since 1880. The trend for certain calendar months changed more than others (discussed below). annual time series from version 3.2.1 is almost identical to the series from version 3.2.0 and that the 1895-2012 annual temperature trend remains 0.13☏/decade. temperature is 0.01☏ higher than reported in early January, but still remains approximately 1.0☏ warmer than the next warmest year, and approximately 3.25☏ warmer than the 20th century average. The net result of this new version of GHCN-M reveals very small changes in temperature and ranks. With this update to GHCN-M, the Merged Land and Ocean Surface Temperature dataset also is subsequently revised as MLOST version 3.5.3. On February 14, 2013, NCDC fixed this error in its software, included an additional improvement (described below), and implemented both changes as GHCN-M version 3.2.1. ![]() This led to small errors in the reported land surface temperatures in the October, November, December and Annual U.S. See a spatial depiction of East-West precipitation in Kansas.An omission in processing a correction algorithm led to some small errors on the Global Historical Climatology Network-Monthly dataset (GHCN-M v3.2.0). ![]() Source: Statewide data obtained from the NCDC.

Both annual precipitation totals and temperature averages have a positively skewed distribution.Ĭlimogram for Kansas based on the period 1895-2011 (Blue bars = precipitation (mm), Black line = temperature (☌). Inter-annual variability is large with 1054 mm in 1951 whereas 391 mm was the lowest annual precipitation amount in 1956. In addition, the region is characterized by extreme short-term and long-term variations in weather and climate. Over 72% of the average 701 mm annual precipitation total comes during the warmer six months of the year with the peak in late spring. Precipitation ranges from 105 mm in June to 18 mm in January. The lowest annual value was 11.0☌ in 1912 whereas the warmest was 14.2☌ in 1934. The statewide average annual temperature is 12.4☌. Statewide average temperatures range from -1.6☌ in January to 26☌ in July (Figure 1).
