Improved Blizzard is a Mage talent that gives the Blizzard spell a chill effect, slowing movement speed by 30%, 50%, or 65% at max rank, for 1.5 seconds. This talent is used primarily for frost AoE grinding, but can be quite useful in PvP, for snaring a large amount of players at once.
At max rank, Blizzard will be the mage's strongest snare spell, surpassing the 50% of Cone of Cold. Because snare effects do not stack, this means that Improved Blizzard, with its short 1.5 second duration, cannot be overwritten with other snares until it wears off. This is an important consideration for some situations, and some mages prefer only two points, to guarantee that Cone of Cold will always apply a chill.

Tips and tricks
Improved Blizzard makes the Blizzard spell an effective snare, but at a large mana cost. If you want only the snare effect, use Blizzard (Rank 1). This chill will also proc Frostbite on each tick.
