oxygen disassociates from haemoglobin more rapidly at higher temperatures, for example just after exercise, therefore the O2 needs to be replaced quickly for respiring cells and it's more efficient to increase breathing rate with shallow breaths than try to take lots of deep breaths, which would tire you out after a while! this is also loosely coupled with the fact that respiring cells are more active and need more O2 at higher temperatures (functioning increased to a limit by thermal energy), so the demand for oxygen along with the quick release from Hb is why we breath faster and shallower when temperatures rise.
