In this work, the way of definition of connection of a temperature field in different spatial scales is offered, and global and regional structures of a temperature field are allocated. For a global temperature field the scale, characterising the Asian territory of Russia (ATR) has been chosen. For revealing of connection of regional fields at the first stage spatial classification has been conducted, then connection of a field in each computed structure (class) were defined. It is shown that classification considerably increases connection of a field in various parts of ATR.
