Locked up might cause daytime temperature drops in the twin cities – Newspapers| Instant News

ISLAMABAD: Locking and limited traffic may have caused a decrease of more than 10pc in daytime temperatures in twin cities.

The positive effects of global locking efforts to limit the spread of the corona virus to nature and the environment have been reported worldwide, and also have similar effects in the region.

Official figures from the Met Office show that the maximum temperature in Islamabad fell by 12pc in April, with an average temperature of 26.8 ° C.

The maximum average temperature in Rawalpindi is 27.3 ° C, 10pc lower than normal.

A senior Met Office official said that the drop in daytime temperatures was not supported by technical reasons other than limited human intervention.

“Even rainfall in the Rawalpindi urban area has been below normal, but heavy traffic, small heat transmitting units and even human breathing in the immediate area create hot clouds over densely populated cities,” the official said.

The official added that there was no significant change in nighttime temperatures, as a minimum temperature

in Islamabad 2.3pc is lower than usual while the situation in Rawalpindi is the opposite.

Met Office records show that the average minimum temperature in April is 16.1 ° C, 2.1pc higher than the average. Rainfall

in Rawalpindi around 56pc below normal, at 28.1 millimeters. Islamabad, however, received slightly above normal rainfall – 63mm – in April.

With the beginning of summer in early May, temperatures will likely be normal next month.

The Met Office estimates that two to three rainy seasons are in May with an isolated system coming from the west.

However, if locking continues in May, rain will cool the area to the north. As the southern part of the country will witness temperature spikes, north-south temperatures

Gradients can cause dust storms and whirlwinds in central and southern Punjab and northern Sindh.

The official said: “A similar pattern is seen on Saturdays even in Islamabad, when rain starts with cold droplets accompanied by winds from the west but soon the south wind pushes back the clouds to bring warm, heavy rain after a pause of a few minutes.”
