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.
