Understanding Weather – not predicting – 22 June 2012

What happened?
As the week progressed, the daily synoptic pattern grew in complexity.
The persistent turbulence as presented by the upper air charts reflecting the contrasting airflows predicted the formation of an elongated upper trough west of the sub-continent over the Atlantic with a tenuous link to the similar trough departing just south of the continent. This new cut-off vortex developed in intensity, extending throughout the troposphere to above the 40000 foot (above 200hPa) range. Such depth does much to provide an air circulation of notable significance. Some tropical air were fed across the interior but very high up.
By Monday evening, associated cloud patterns were forming and local showers were noted.
The lower levels, sea-level to some 5000 feet, were reacting to the squeeze between the western edges of the departing cold front trough and the anticyclonic ridge thrusting its way across the South but also around the vortex core which had, in the past few days, become separated from its original parent vortex away to the south. This matches the description of a complex low pressure system.
It fits the given situation here and, when coupled with the adjacent upper air complexity, only serves to test the imagination with regard to the radically turbulent scene holding sway across a considerable area above the western sub-continent and the adjacent ocean.
While the direct cause for this complexity may be difficult to assess, it does bear the hallmarks closely linked to the overall shift of airmass presence and the matching ability for these departures from the norm to appear on the same weather stage, virtually side by side: evidencing the impacts brought about by the shift or change of climate zones and their patterns.
For our south-east, from the Windhoek area southward, widespread to general shower activity was there was recorded. Some rainfall measures over both the pre-Namib and the Kalahari exceeded 20mm.
With the upper air activity and subsequent vertical mobility, the interior recorded milder days but in the South, zero degrees in the morning was the norm.
What’s coming?
While the current pattern departs during Friday, a new upper vortex develops by weekend again west of the Cape. Weather activity may be confined south of the Orange, but active weather can develop within the cold under-cutting currents on its western side and the tropical presence on its northern side. Very light rain may be encountered in southern Namibia.
Southerly low level inflows arrive by Saturday, with a wind flow switch bringing warmer days in the new week ahead the vortex and cold front which appears by mid-week. Early in the week, cooler air penetrates from the east into the Kavango area at least while our north remains comparatively warm. Over night frost looms for the southern parts. The expected weather divides itself into a northern half and southern half pattern – warmer and colder.

Following reverse listing, public can now acquire shareholding in Paratus Namibia


20 February 2020, Windhoek, Namibia: Paratus Namibia Holdings (PNH) was founded as Nimbus Infrastructure Limited (“Nimbus”), Namibia’s first Capital Pool Company listed on the Namibian Stock Exchange (“NSX”).

Although targeting an initial capital raising of N$300 million, Nimbus nonetheless managed to secure funding to the value of N$98 million through its CPC listing. With a mandate to invest in ICT infrastructure in sub-Sahara Africa, it concluded management agreements with financial partner Cirrus and technology partner, Paratus Telecommunications (Pty) Ltd (“Paratus Namibia”).

Paratus Namibia Managing Director, Andrew Hall

Its first investment was placed in Paratus Namibia, a fully licensed communications operator in Namibia under regulation of the Communications Regulatory Authority of Namibia (CRAN). Nimbus has since been able to increase its capital asset base to close to N$500 million over the past two years.

In order to streamline further investment and to avoid duplicating potential ICT projects in the market between Nimbus and Paratus Namibia, it was decided to consolidate the operations.

Publishing various circulars to shareholders, Nimbus took up a 100% shareholding stake in Paratus Namibia in 2019 and proceeded to apply to have its name changed to Paratus Namibia Holdings with a consolidated board structure to ensure streamlined operations between the capital holdings and the operational arm of the business.

This transaction was approved by the Competitions Commission as well as CRAN, following all the relevant regulatory approvals as well as the necessary requirements in terms of corporate governance structures.

Paratus Namibia has evolved as a fully comprehensive communications operator in Namibia and operates as the head office of the Paratus Group in Africa. Paratus has established a pan-African footprint with operations in six African countries, being: Angola, Botswana, Mozambique, Namibia, South Africa and Zambia.

The group has achieved many successes over the years of which more recently includes the building of the Trans-Kalahari Fibre (TKF) project, which connects from the West Africa Cable System (WACS) eastward through Namibia to Botswana and onward to Johannesburg. The TKF also extends northward through Zambia to connect to Dar es Salaam in Tanzania, which made Paratus the first operator to connect the west and east coast of Africa under one Autonomous System Number (ASN).

This means that Paratus is now “exporting” internet capacity to landlocked countries such as Zambia, Botswana, the DRC with more countries to be targeted, and through its extensive African network, Paratus is well-positioned to expand the network even further into emerging ICT territories.

PNH as a fully-listed entity on the NSX, is therefore now the 100% shareholder of Paratus Namibia thereby becoming a public company. PNH is ready to invest in the future of the ICT environment in Namibia. The public is therefore invited and welcome to acquire shares in Paratus Namibia Holdings by speaking to a local stockbroker registered with the NSX. The future is bright, and the opportunities are endless.
