The state of Andhra Pradesh has a large coastline and it shares its borders with Tamil Nadu, Odisha, Karnataka Telangana and Chhattisgarh.
Otherwise, the state of Andhra Pradesh has two sub divisions namely Rayalaseema and Coastal Andhra Pradesh. However, both the subdivisions have different climatology and topography.
Rayalaseema lies in the interiors and has four districts including Anantapur, Chittoor, Cuddappah, and Kurnool.
Meanwhile, Coastal Andhra Pradesh has more districts including East Godavari, West Godavari, Guntur, Nellore, Krishna, Prakasam, Srikakulam, Visakhapatnam and Vijayawada, all of these having a coastline.
Unlike during the pre-Monsoon season when a trough extends through Southern Peninsula and is a semi permanent feature during this time. However, Monsoon does not have any such system for the interiors of Andhra Pradesh.
In fact, most of the prominent systems are not in the direct range of Andhra Pradesh. The coastal parts of the state still receive rainfall due to the systems forming in the Bay of Bengal.
This time also Rayalaseema has not been able to receive rainfall at all due to which the deficiency in terms of rain is at a massive - 47% which is also the highest deficient figure in the entire country. Coastal Andhra Pradesh has performed much better and is currently observing a surplus of 2%.
Here is a detailed summary of how Monsoon has performed in Andhra Pradesh so far:
The only time Rayalaseema sees rainfall during the Monsoon season is due to the south-westerly winds in the form of Monsoon surge. Coastal parts still manage to record rainfall due to the Monsoon systems forming in the Bay of Bengal and a trough which at times develops along the East Coast.
Rayalaseema does not lie in the proximity of the West Coast or the East Coast. Thus, troughs along either sides have no effect over Rayalaseema. Monsoon systems also travel much north as compared to the location of Rayalaseema.
In fact, the strength of Monsoon surge also depends on the Monsoon systems. When the systems are not present, surge remains weak, resulting in subdued rains over Rayalaseema.
Now also, no rains are expected to occur over Rayalaseema for at least a few more days which will only result in an increase of the deficient figures.
