NOTES ON YORK METEOROLOGY FOR 1892.

COLD AND HEAT IN APRIL, 1892. 
The barometer was high, the mean being 30 02 3 against an 
average of 29 904 for the fifty years, 1841-90, with which 
comparisons will here be made. Only on the 27th was there 
any serious fall (29*455). This resulted in the storm of cold 
rain (0*63). On the 14th, after the heavy snow-fall, which 
melted to 0 83 of rain, the barometer fell to 29*68. 
For the fourth month in succession there was more snow 
than rain, 0*96 falling in this form out of a total of 1*86, as 
measured at Bootham School. It will be noted that of this 
total, 1*49 fell on two out of the 12 “rainy” days. Thus far 
no warm rain-shower has fallen. 
Only on five days was the wind from southern quarters. 
Temperature, as shown by the mean of the maximum and 
minimum thermometers (44*8° for the month) was 1*1° below the 
average. But this gives little idea of the anomalous nature of 
the month. The maxima average 55*2°, the minima 34*4°. 
The former is 1*6° in excess; the latter 3*6° deficient. The 
latter record was only surpassed in 1842, just fifty years ago, 
when the maximum (55*7°) was even higher. But the range 
of nearly 21° is extraordinary. 
It is, however, surpassed by the daily records. Frosts 
occurred on no less than 22 nights, snow falling on 7 days. 
On the 16th, 24° was recorded and 20° on the grass. This 
was surpassed only last year (22°) ; in 1881, when 22*4 was 
recorded, and in 1842 when the minimum was 23°. On the 
14th, also, 25° was touched; besides the above, this has been 
thrice equalled, but not surpassed. In 1864-5-6, 1870 & 1872, 
there was no frost registered in the screen. 
The warmest day was the 21st (mean of 8 a.m. and p.m. 53°); 
until then, indeed, the hottest days were January 30th (49°), 
and March 17th and April 5th, with means of 50°. The 22nd,
