The Mediterranean: Abnormal high sea surface temperature

This is the hottest we have ever observed. The Mediterranean is now completely outside all previous records. We have never measured this level of heat across the basin at any time of year. It is only July. We usually see the annual maximum in August. pic.twitter.com/rrdWGzkBYE — Scott Duncan (@ScottDuncanWX) July 25, 2023 Anomalías de la temperatura del mar en lo que llevamos de verano. Casi todas positivas e incluso hasta +6ºC en algunos puntos. Continue reading

The recent daily evolution of Sea Surface Temperature in North Atlantic

Last 30 days of sea surface temperature anomalies for the western North Atlantic (with labels). pic.twitter.com/8ygTFE2G6N — Dr. Mathew Barlow (@MathewABarlow) July 21, 2023 last 30 days of sea surface temperature anomalies pic.twitter.com/HPTFeAIz3t — Dr. Mathew Barlow (@MathewABarlow) July 20, 2023 The rate of rising sea surface temperatures (SSTs) in the tropical Atlantic Ocean these past three weeks is kind of mind-boggling. The dashed line indicates the 26.5°C isotherm, a value used as a reference threshold for whether water can support tropical cyclone development. Continue reading
