SINDH WEATHER

A Cyclonic Circulation that is presently at Central India,has brought very strong thunderstorms with heavy rains & what made it so strong? The deep convection within the circulation has enveloped major states of India including Telengana. Another Well marked low pressure is marked over Northeast India that will also boost rains over there in future. We have never seen, this type of convection in deep depression that had invaded Gujarat and Sindh during 2017 monsoon.

Global warming has increased chances of erratic weather patterns that would effect entire south Asia.To demonstrate,how it could be & why?: •Keep in mind,Global warming has increased rate of varying temperatures such as heatwaves & floods in result of rapid rate of glacier melt. Latest observations are hinting that worldwide sea temperatures are rising due to global warming per year so that we can reject by a possibility that by next 50-100years,monsoons could get more strength with hilarious and deadly heatwaves preceding monsoons.Floods could be triggered due to glacier melt and rise in sea level. Tropical weather could get more intensified,as due to rise in Arabian sea temperatures per year,Tropical cyclones could be potential in strength. Experts at Pak Weather Info,believes that in future,global warming can cause virulent weather patterns in Pakistan in future.

Karachi lies in the arid climate.Karachi lies in the coast and enjoys fresh sea breeze sometime during hot months such as may and June whereas other parts of Sindh remains under impact of deadly heatwave.Sometimes,due to some factors like tropical cyclone alters the direction of sea breeze causing a temporary heatwave there but April,May and June are considered as hottest months there.Karachi mainly receives less rains during the months of monsoon and the cause is inversion layer that surrounds the city during most time of years until any monsoonal low or weather disturbance I.e western disturbance breaks that inversion layer. There are two factors that alters the weather over Karachi. •Western disturbance •Tropical cyclones •Monsoon •Local heat convection •Western Disturbances:- Western disturbances are common to  invade the city during winter season and cause rain of varying intensity (depending upon conditions and intensity of western disturb...

After a long time,something interesting seems for upper sindh during next 24 hours,owing to a western disturbance over northern Pakistan,sending heavy pulses that have potential of causing 'dust-thunderstorm' at isolated places of upper sindh during next 24 hours. This is not a first time that any WD showing its affects on upper sindh however,upper sindh lies in WD zone so this is quite normal. Rainfall will be accompanied by thunderstorms (est: 2-3mms).

Since city has started receiving monsoon rains,owing to a cyclonic circulation that has caused intrusion of strong monsoon currents at lower levels there. Mumbai has got 103.2mm during 4 hours,as according to the time of India.Heavy rains and thunderstorm caused citizens to awaken from sleep. But this is not a end,more monsoon downpours could occur during next 24 to 48 hours.

Owing to a cyclonic circulation at northeast India,Mumbai has been witnessing heavy rains with thunderstorms because cyclonic circulation has increased monsoon currents over there. Overall there is no any effect of this system here in Sindh but this post is just for information purpose only. Presently,Mumbai vicinity has started getting thunderstorm with rain.

We all have heard two terms 'western disturbance' and 'monsoon'.But most from us don't know what they exactly are and how they both differ from each other. Monsoon is a seasonal reversal of winds occurring from June to September. Monsoon occurs for temporary period but is associated with wet summers however,dry winters.On the other hand,western disturbance is extra tropical disturbance/cyclone originating from Mediterranean sea & make its journey towards Pakistan after crossing Iran, and Afghanistan.Unlike monsoon,western disturbance moisture is carried in upper atmosphere & western jet help it to transport to another place,due to which WD have less or negligible convection.But don't be confused,WD in most cases have high convection that leads to flooding rains (usually during interaction with monsoon currents). Unlike,monsoon currents which are usually seen in low levels of atmosphere,WD are usually found in mid & upper levels,in rare cases can b...
