British Rainfall 1896 page 22
inclusive, was extraordinarily small,* scarcely 80
per cent. of the average.
XI. BB. - When, at the end of 1864, Mr. Fletcher recommenced
observations at The Stye, the old gauge (XI. AA) had
probably disappeared; because Mr. Wilson assures us that
what is now known as XI. A "has always been in the same
position," and he places it N.W. of B. Had even the ruins of
the old gauge been seen by Mr. Fletcher, he would doubtless
have placeed (sic) the new one on the identical spot. The
erection of this gauge was nearly concurrent with the advent
of two of the wettest years in the Lake District, and we
consequently see totals exceeding 200 inches, viz.:-
|
|
1866 ... | 224.56in. | 1872 ... | 243.98in. | 1882 ... | 202.50in. |
1868 ... | 207.49in. | 1877 ... | 235.52in. | 1890 ... | 202.05in. |
|
|
The average given by this gauge is 179 inches; if the
fluctuation of rainfall at that wet station is similar to
that usual in England, we can compute the probable fall in
the driest and in the wettest year, and see how nearly the
extremes have been approached -
|
|
| | Theory. | Fact
and Date. |
Gauge AA | Driest year | 99in. | 99.16in. in 1855 |
Gauge BB | Wettest year | 260in. | 243.98in. in 1872 |
|
|
It is therefore extremely improbable that there will ever be
a drier year than 1855, but is likely that the great fall of
more than 240 inches (20 feet; 6,197 millimetres) will be
exceeded.
XI. CC. - Knowing of the uncertainty as to the indication of
snow by the pattern of gauge XI. BB, we induced Mr. Maitland
in 1879 to put down one of the large 8-inch float gauges
(Fig. V. facing p.22 of British Rainfall, 1895), it
did not work well, and was very troublesome in frost, but on
the whole it gave rather more than XI. BB; its mean was 184
inches, and its position is believed to have been near XI.
B.
XI. DD. - This was fixed in 1885 in order to see whether the
fall increased or decreased south-eastward; it has collected
less in every year until 1896. We are not sure that this
gauge has always been in the same position; we rather fear
that there may have been some confusion when, at the end of
1895, two additional gauges were erected. We always regarded
this gauge as occupying the position now occupied by XI. D,
but according to Mr. Wilson it was at XI. B. However, it
shows a decrease to the S.E.; and as regards
* See British Rainfall 1867, p.18, and
British Rainfall 1895, p.25; which shows the mean
ratio for those years to be only 83 per cent.
