Mango Temperature effect on blossom

I have a mango tree in my banglow. Now it is in  blossom  emergence mode.  I have observed that  the emergence of blossom  is not uniform. However it is profuse on the branches resting on tin sheet roof. This may be due to availability of excess temperature as a result of heating of roof.  Present cold air may also controlling adverse effect to some extent.  I a doubt that  if this condition continues it may have adverse effect on mango fruit during development especially initial  stage.
Can some one explain me the reasons for
• such phenomena  of irregular blossom.
• What is the role of excess temperature on flowering in plant.
• where my fear of adverse effect of continued high temperature in the area around blssomis true or not.
The scientific  reasons for the same may kindly be indicated.
