Spain - September 24th, 2009

Rivers flowing down from the Cantabrian Mountains in Spain’s Province of León are flanked by bright green agricultural areas. The two principal rivers visible are the Óbrigo (left) and the Esla (right), which converge below Benavente.

The Esla River is a tributary of the Duero River which starts in the Cantabrian Mountains and is 286 km in length, crossing from north to south the provinces of León and Zamora. It is the largest tribuary of the Duero in terms of discharge; in fact, at its mouth, it has a greater discharge than the Duero itself does at that point.

The Órbigo River, also flowing through the provinces of León and Zamora, begins at the convergence of the Luna River and the Omaña River in the town of Santiago del Molinillo. Green fields extend far eastward from its banks, almost converging with those along the banks of the Esla.

Castilla y León, Spain - radar image

Part of the Autonomous Community of Castilla y León is visible here. The land becomes increasingly flatter and more arid moving from west to east, evidenced by the color change from dark green to golden yellow.

This region of Spain has a Continental Mediterranean climate. It is similar to a Mediterranean climate, but with some typical features of a Continental one, such as cold, dry winters and warm summers. The higher the altitude, the stronger the Continental aspects of this climate become.

There is an 18.5°C difference between average temperatures in winter and summer. In summer, temperatures are often above 30°C, while frosts are common in winter.

The amounts of rainfall, on the other hand, are very similar to those of a Mediterranean climate: 400-600 mm, with peaks in autumn and spring.

The Barrios de Luna Reservoir and the Luna and Omañas Rivers are visible towards the center of the color image. The ASAR (radar) image shows a smaller area, focused around the reservoir.

The radar allows the rivers (black) and the cities and towns (bright white) to be observed more clearly. The decrease in altitude moving west to east can be discerned from the gradual lightening of the grey landscape.
