It is called the nitrogen cycle and begins with the reaction between N2 and
O2 with lightening as the initiator forming NO which reacts with H2O forming
HNO3 which then falls to earth with either rain or snow...




While there is a certain amount of NO in the atmosphere during the
winter, it is higher in the summer. One reason for this is that
lightning does not occur as frequently in the winter. However,
alternative sources for NO include automobile exhaust, which is present
year round. NO is formed by any high temperature combustion using air as
the oxidizer.
