Understanding Weather – not predicting – 20 December 2012

What happened?
”Weather” is renowned for its ability to achieve the unusual and do so with scant advice to the onlooker. A week ago a quite familiar synopsis was present with a moist band to the north and an active, cut-off vortex above our southern skies. These patterns usually depart quickly, clearing away in a matter of hours.
But there was much surprise to follow.
The northern pattern drifted westward, limiting precipitation quite considerably across the northeast: few showers were noted and the activity to the west was also limited. Diversity of airflow patterns across the area and with altitude emerged as the pattern unfolded. The slack wind-flows one finds in proximity to the zone of convergence which characterises the equatorial rainfall belt do bring about a level of stagnation. Both the Cuvelai and Kavango catchments only had downpours typical for this time of year.
To the south, though, the cut-off aspect provided for a shallow (scant vertical extent) anticyclonic core to thrust south of the upper vortex so to make it even more “cut off” before continuing its eastward move. Such a delay enables activity (cold air undercutting for instance) to be enhanced: considerable downpours resulted. This is quite normal but in this case the cut-off feature is unusually late in its time range and whether or not it can tap a moist tropical air to power its activities may not readily be identified.
Such patterns are not long-lived. In this case barely 36 hours saw the full development and consequent departure, but in so doing the pattern built a storm area which brought 50mm measures within a single rainfall day. For the Karasburg area and the month of December these (scarce at any time of year) are not previously on record. A further bonus lies in the spread of the rain across some hours rather than the (to be expected) minutes, indicative of such downpours. More distant activity recorded similar unusual falls to the east with both Aroab and Gochas’ detail topping 20mm.
Already this new rainfall year has seen some unusually heavy falls spread across hours rather than minutes providing penetrating values rather than run-off water.
For the in-between remainder, December provided the heat and the promise, coupled with increasing cloud, to see out the week.
What’s coming?
The pre-Christmas outlooks maintain the spread of moist air above much of the country, departing briefly but returning quickly in response to the mobile synoptics close to and around the Cape.
A new upper air cut-off vortex appears above the east Atlantic during the weekend, collapsing before mid-week as it nears the Cape, enabling the new surface ridge to push and redevelop, with a resurgence of lower level maritime air toward the shower belt building east of the interior low pressure area.
Middle level tropical air turbulence and convergence persist above both Angola and Zambia maintaining moist air presence adjacent to our air space: an amenable situation for the time of year!
From this scribe, Happy & Holy wishes for the season until 2013

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

Promotion

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.
