Frequency Of Hot Days in Sapporo City, Hokkaido Prefecture, Japan

Hi, everyone.

As you know, Tony has created many charts showing how the frequency of heat wave days has declined in the USA.

Today, I’d like to show Sapporo City‘s number of days over 30℃ for the period January 1 to August 31.

Data Source

As you can see, there has been no trend since 1919.

However, last year the Asahi Shimbun says that even in Sapporo, the temperature has been over 30℃ more frequently recently.
Obviously the newspaper ignored the data.

    Thanks Kirye,
    How do the various peaks and troughs compare with the US data set? Would it be possible to overlay a N. American graph as I’d be interested to see if there is a relationship with the mid-thirties heat waves Tony points to for the USA?

    In petroleum engineering well production and pressure analysis, we plot data on a semi-log graph. I was told because the data was from a multiplicative process, better estimated future volumes or pressure were determined. Have you plotted temperature data on a semi-log graph versus time?

    Kirye, many thanks. There is supposed to be ‘global warming’ of a catastrophic nature happening and statictical scientific confirmation like this, that there is no evidence at all that other parts of the Planet are definitely not undergoing undue warming, no more than the usual cyclical changes in the Planet’s weather, is both heartening, reassuring and very welcome. Keep these graphs coming about Japan and other countries of the Orient so that these can be circulated to interested parties in the Western World who constantly need reminding that supposed global warming on account of changes in the Planet’s climte is just not true. Good to have you on board with Tony….
