Precipitation forecast accuracy exceeds 93 pct
SEOUL, July 25 (Yonhap) -- The nation's weather agency said Monday that its precipitation forecast accuracy jumped to over 93 percent in the first half of this year, pushing up public satisfaction with meteorological services.
During the January-June period, the Korea Meteorological Administration (KMA) said it correctly predicted more than 93 out of every 100 incidents of rain or snow, bringing up its precipitation forecast accuracy to 93.1 percent.
The accuracy rate compares with 85.2 percent compiled for 2006, while the ratios for 2009 and 2010 stood at 91.9 percent and 89 percent, respectively, the KMA said.
"Accuracy above the 90 percent level represents a very high average," a KMA official said. "Prediction accuracy tends to go down somewhat during the summer season with frequent rainfall."
The KMA's temperature forecasts were also more on target with its predictions of daily highs during the year's first half showing a difference of only 1.3 C with actual recorded levels, it said.
The prediction-observation gap reached 2 C in 2006 before narrowing to 1.9 C the next year and down to 1.4 C last year, according to the agency.
The recent gains in forecast accuracy have enhanced public satisfaction, the KMA added.
Public satisfaction with the national meteorological services reached 82.3 points in a survey in which about 9,000 respondents were asked to rate their satisfaction on a 0-100 scale during the first half of 2011.
The same poll, conducted by private research provider Gallup Korea, posted 78.3 points last year and 67.4 in 2009, according to the KMA.
