OSEM underestimated the southwesterly wind around the trough, which slowed the eastward movement of Ian in the marginal stage (Fig. 3c). Cape Town - The South African Weather Service (SAWS) has advised that the country is in no immediate danger from tropical cyclone Batsirai currently affecting the southern Indian Ocean. Ensemble forecast experiments with different reanalysis data confirmed that additional Arctic observations sometimes improve the initial conditions of upper-level troposphere circulations. Wu, C.-C. et al. the equatorward movement of the cold air of high latitude a dominant factor in mid-latitude weather. It is important to note that Mid-latitude are associated with the westerlies and Tropical cyclones with the easterlies.

Some PV fields are masked to highlight temporal evolution of targeted PV. The Cape Town Weather Office said the storm would predominantly affect the eastern parts of Limpopo and Mpumalanga. Naike says most of rainfall we receive in the Western Cape comes from mid-latitude systems which provide cold fronts and other cyclonic flows that give us wet weather. J.

Tropical cyclone (TC) activity in the Mozambique Channel from January to March 2012 resulted in five landfalls that affected Madagascar and southeastern Africa. Kazutoshi Sato. Google Scholar. For September, we created CTL1, OSEMGC, OSEM, OSEG, and OSEC reanalysis datasets from 15 August to 28 September 2016, and for August, those of CTL2, OSEBAP, OSEB, OSEA, OSEP, OSEMID, and OSETRO were created from 26 July to 30 August 2016. Also referred to as an Extratropical Cyclone, these are large areas of low pressure that form in the mid-latitudes (30-60 degrees N or S of the equator) and rotate counterclockwise in the northern hemisphere.

There were differences in geostrophic wind speed between CTL2f and OSEBAPf over southern Japan (Supplementary Fig. High school past paper practice. In the case of large storm systems such as cut-off low pressure systems, mid-latitude cyclones and cold fronts prevalent in the Western Cape, heavy rainfall can last for 3 days and more per storm. We conducted 4.5-day integrations in experiments from 0000 UTC 25 August, 0000 UTC 14 September and 0000 UTC 24 September for the Lionrock, Ian and Karl cases, respectively.

Physical mechanisms of tropopause polar vortex intensity change. A.

An automated cyclone finding program was used to identify cyclone centres. In addition, near the western coast of Africa on 15 September, a tropical depression grew into tropical storm Karl, which moved northward off the east coast of North America27 (Supplementary Fig. The circle radius indicates the average difference of the distance between the locations of the ensemble mean and of each member.
