Very heavy rains in the Karakoram Range has flooded 1/3 of Pakistan downriver. Very heavy rains in the central Himalayas so late in September also has caused floods, after a summer sowing season marked by intense drought.

What global meteorological conditions might have influenced these events?

Do you also study the Monsoon Trough that build up over the Ganga plains and causes lower than normal rainfall underneath it?  2 streams of descending air, one from the Himalayas, the other from central India?  Thanks in advance
