Algae report number 3, 2011

ReportsOceanography
The genus Dinobryon dominated in the Skagerrak area, the dominance was especially pronounced at the outer station Å17. Low chlorophyll a values clearly indicated that the spring bloom had now ended. Low chlorophyll a concentrations were also recorded in the Kattegat area. Few species were recorded Last updated:

Rapid sea ice change events in regional Arctic scenario experiments

rapid loss events. Individual events diverge and can be dominated by summer warming as well. The most extrem loss events are connected to stronger influence of the so-called “dipole anomaly”, a meridional surface air pressure anomaly pattern. In the current version of the Arctic climate model, sea ice Last updated:

Automatic cloud analysis - the Nowcasting SAF project

MeteorologyResearch
The SMHI meteorological group is involved in the Nowcasting Satellite Application Facilities (NWC SAF) initiated by EUMETSAT. The NWC SAF derive and develop products for nowcasting and very short range forecasting. Last updated:

Royal wedding weather throughout history

NewsMeteorology
if local showers are in the offing then a definite forecast can only be made a few hours in advance – if that! It could be interesting to look back at the statistics on the weather in Stockholm for 19 June over the last 20 years. Then we can see that rain fell on more than half of those days, but Last updated:

Algae report number 2, 2011

spring bloom was close. Apart from this, there were mostly small flagellates, ciliates and small spheric colony forming cyanobacteria in the phytoplankton samples. Enhanced integrated chlorophyll concentrations were found in the Southern Baltic. Last updated:

Extreme waves

Oceanography
In the north-eastern Baltic the risk of meeting the highest waves is greatest, since strong south-westerly winds are common and they have the longest wind fetch. High seas can start to build up south of Gotland. On the west coast the highest significant wave height was 7,7 meter and the maximum Last updated:

Algae report number 1, 2011

ReportsOceanography
higher chl a content was however recorded at Släggö and Anholt E but still within normally low for the season. All stations in the Baltic Sea contained few species with only few cells of each species recorded. The chl a levels were mostly below 1 μg/l which is within normal for the season.
