What is Dura Mater?
Dura matter is tough outer coat on the brain. Inside it you have arachinoid matter. Innermost is pia matter. Outer coat of dura matter goes along with the inner layer of skull. Inner layer goes with the folds of brain. So you have falx cerebri. Above of which you have superior sagittal sinus and below is inferior sagittal sinus. Superior sagittal sinus is between outer and inner dura matter and inferior sagittal sinus is fold of inner layer of dura matter only. Then you have tentorium cerebelli and falx cerebeli. So you have cavernous sinus, superior and inferior petrosal sinus. Transverse sinus and sigmoid sinus Draing into internal jugular vein, through jugular foramen. ( Along with 9,10 and 11th cranial nerve.) Then straight sinus at the inferior border of falx cebri, posteriorly. And sinus coming from cerebellum below. This tough fold protects the delicate brain by forming compartments in it. It also helps in flow of venous blood, by forming venous sinuses.

How does barometric pressure affect people?
If the barometric pressure drops suddenly, as it does often before a storm, and your sinus passageway is blocked, the higher pressure in the sinus will press on the bones surrounding it to cause a horrible headache. When your nose is stuffy, the inner linings of your nose are swollen, and the same swelling can shut the sinus passageway, preventing air pressure inside your sinus from changing to balance the pressure outside, and you can develop a sinus headache. from: http://www.drmirkin.com/morehealth/1254.html
