METEOROLOGY IN EUSSIA.

The temperature of the winter is also higher ou the western coast of 

 Nova Zembla than in the northeast of European Eussia and Western 

 Siberia. It has been found to be 5.7 on the 74P north in isTova Zembla, 

 while it is — 6.5 at Berezov, (64° N.,) 1.6 at Ischim (56° N.,) and 10. 2 

 at Kasalinsk, on the lower Syr-Daria, (46° N.,) so that it is only 4^o. 

 higher, for a difference of 28° of latitude. The mildness of winter tem- 

 perature on the Arctic Ocean is also illustrated by the fact that, while 

 this ocean does not freeze so far as the Swjotoi Noss, the Caspian and 

 Azov Seas, in a latitude of about 46°, freeze to a great extent. 



The observations made in Russia furnish us with the means of tracing 

 the changes of temperature from east to west, from the Atlantic to the 

 Pacific Ocean. Generally the winter temperature decreases as we ad- 

 vance into the interior of the continent from west to east, and increases 

 a little on the eastern shores of Asia. Yet, being much lower there than 

 in Western Europe, the temperature iu the interior is a little higher in 

 summer than near the Atlantic, and decreases very rapidly near the 

 Pacific, being much colder there than anywhere else ou the same par- 

 allel in Europe or Asia.

The difference between the limited climate of the shores of the Atlan- 

 tic and the excessive climate of the interior of Eastern Siberia is strilc- 

 ingiy illustrated by this exami^le. The difference of the mean temper- 

 ature of January and July in the last place is more than 100°, (January, 

 — 41.45 J^^ljj 63.3.) Unfortunately we have no observations on the 

 shores of the Pacific north of the 59th degree. The winter temperature 

 would certainly be much higher there than at Jakutsk.
