Bay of Bengal Low – Update 30th December 2014

December 30, 2014 12:00 am admin 0

After providing some much needed rains to Chennai and surrounding areas yesterday the Well Marked Low has moved further North and is now ESE of Chennai at about 400 kms away. As it moves further North it would enter into high shear zone which could prevent further intensification majorly.  Models expect the disturbance to further move towards Odisha / WB.   Considering the shear and the possibility of dry air impacting the system beyond 15N it looks extremely difficult for the system to survive its north journey all the way till Odisha / WB in its current intensity. So what [Read More]

Bay of Bengal – Low Pressure Update

December 28, 2014 12:00 am admin 0

The disturbance over Bay of Bengal has moved to better conditions in South Central Bay and has picked up some intensity over the last 24 hours or so.  Though it is still lacking in a proper structure yet it has moved into an area with better shear conditions which should aid it to build some organization & intensify into a possible depression shortly. The Depression is expected to move in a Northerly direction along the coast of Tamil Nadu, this northward movement should give some decent rains to coastal Tamil Nadu aided partly by the moisture incursion from Western Pacific.

Bay of Bengal Disturbance – Disappointing Season continues

December 26, 2014 12:00 am admin 0

As with pattern this year, events dont seem to work in favour of Chennai & North Tamil Nadu.  While the majority expectation was for the low to form closer to Andaman Islands, the low has developed SE of Sri Lanka. With the expected steering pattern available it is at a location where it cannot develop into a system of good intensity and provide wide spread rains. Some  models expect the system to move NE in search of warmer waters and possibly take up the energy of another subdued vortice (the one orignally expected to develop), this process of power struggle [Read More]

Delay in Low Pressure Area formation in Bay of Bengal with Ever Changing equations

December 24, 2014 12:00 am admin 0

While weather enthusiasts are eagerly looking at Bay of  Bengal for the next disturbance to form, the bay is moving things at its own pace with a lot of factors inter playing.  As confirmed by IMD there is a Low Pressure trough SE of Sri Lanka along the equatorial waters and another trough west of Andaman. These two have there own embedded vortices in them.  Its these two vortices that are trying to establish dominance and take up the mantle of the next disturbance in Bay of Bengal that’s creating an equation that is changing by the hour and keeping [Read More]
