blob

On a screen, they saw a series of colorful, balloon-like blobs.

One such potential influence to our winter weather is a 'warm blob' in the Pacific Ocean which could favour higher pressure and colder conditions developing in Europe.

A few generations ago, the ultrasound would show a grainy blob.

But all this extra heat in the so-called "warm blob" may have the opposite effect in the UK, possibly making a colder start to winter more likely, some researchers believe.

This phenomenon involves cooler, heavier blobs of plasma that condense high above the Sun's surface and then plunge back down.
