|Zeus and his thunderbolt|
The Mayans too had a god of rains and lightening, by the name of Chac. Chac besides being a rain god was also a fertility deity like many above as rains were very closely linked to fertility.
According to the Nordic Mythology, Thor was the god of thunderstorms and used to create thunder with his magical hammer, but they had a separate god in Freyr as their god of rains as well as fertility.
The influence of the Chinese dragons can be seen in Japanese mythology, where too the dragons were seen as water deities who were associated with rains and were often depicted as large serpentine creatures with clawed feet. In the Shinto religion, these dragons are associated with agricultural rituals and prayers for rain and the success of the fisher-folk.
As I mentioned earlier, not all associations of rains is with romance and getting cozy. Rains affect livelihood and had far larger and long-lasting implications for our ancestors and that can be seen in the depiction of rain-gods and in some rituals of the past. Sometimes the rituals seem inhuman, but let us not forget the times and the cultural milieu of the times and above all the faith-system, which is the most important aspect of every culture.
