(meteorology)
Any horizontal line along which horizontal convergence of the airflow is occurring. Also known as asymptote of convergence.

ITCZ is a convergence line between northwesterly wind and easterly moist wind that cause rising currents of air leading to formations of convective rainy clouds.
They also found that, for higher wind speeds, the sea breeze convergence line is shifted away from the center of Salento Peninsula similarly as found in the present study over the AP.
A relatively strong convergence line forms north-west to south-east by Wednesday which will be accompanied by windy conditions over the escarpment, and the adjacent interior.
The above analysis suggests that newly developed convective cells correspond to cold centers within the surface convergence line. The stronger the cold center, the more severe the convective system and the heavier the precipitation.
On 16 August 2004 high humidity in the troposphere, combined with a stationary convergence line, led to the development of deep convective clouds that produced intense rain over a period of about 4 h, with up to 183 mm of precipitation recorded over a 5-h period, resulting in flash flooding in the village of Boscastle in southwest England (Golding et al.
During the week, a very prominent convergence line developed, both on the surface, and up to about 25,000 feet.
This trough follows the convergence line more or less from Ruacana to Aroab.
Were one to look up, the thin layer of cloud showed that the upper air flow was from north-west to south-east, following the convergence line which is typical for Namibia, and very typical for the season.
This is called the convergence line and it loosely defines the interface where the South Atlantic high pressure cell meets the reciprocal lower pressure airflow from the north-east.
When the low pressure from the north meets the opposing high pressure from the south, it creates a visible convergence line with fresh winds blowing from the north-west.
This separation line is known as a convergence line. It is defined by the area where the dominant south-westerly airflow, at surface level, confronts the reciprocating airflow from the north.
north and east of the new convergence line. However, the high pressure cell south of Madagascar remains somewhat weak, possibly creating the space for the trough to stay longer and penetrate our southern regions.
