| Zusammenfassung |
| In this paper temperature series of Japan were statistically analysed in
order to answer the question whether recent climate change can be proved for
Japan; the results were compared and discussed with the global trends. The
observations in Japan started for some stations in the 1870s, 59 stations
are available since 1901, 136 stations since 1959. Modern statistical
methods were applied, such as: Gaussian binominal low-pass filter (30 yr),
trend analysis (linear regression model) including the trend-to-noise-ratio
as measure of significance and the non-parametric, non-linear trend test
according to MANN (MANN's Q).
According to the results of the analyses, climate change in Japan is clearly
shown for temperature over the 100 yr (1901–2000): Annual mean temperatures
increased at all stations from 0.35 (Hakodate) to 2.95°C (Tokyo). The
magnitude of climate change is illustrated to increase over the recent
period 1976–2000. Seasonally, the strongest warming trends were observed
for winter temperatures and also increasing temperature trends prevailed in
summer, with the exception of slightly decreasing trends at only four
stations. |
