Thereafter, the climate shows a small-scale oscillation to drier condition between \*c.\* 1800 and \*c.\* 1500 B.C., followed by a slight reversal to a relatively weak wetter condition, lasting to about 1000 B.C.' (Singh, 1977). - [Previous: v2.c45.294](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c45.294) - [Next: v2.c45.296](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c45.296) - [Up: v2.c45](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c45) --- Source: [https://indike.org/pramana/ins.reference.ghosh-1989.v2.c45.295](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c45.295) · Pramāṇa
