CAUSE FOR DUST

Strong west­erly winds with a speed of 40–50 km per hour, are bring­ing in dust from across the western parts of In­dia that have been wit­ness­ing ex­treme “dry” con­di­tions. The winds have been blow­ing sus­tain­ably since Tuesday, ac­cu­mu­lat­ing the dust.

WHY THE SPURT

There has been in­tense heat and dearth of mois­ture in the north-western parts of In­dia, mak­ing the soil dry. The west­erly winds blow­ing close to the sur­face pick up ground dust and also bring in other ul­tra­fine par­ti­cles from con­struc­tion sites, in­dus­trial ar­eas and ve­hi­cles.

NO MON­SOON IM­PACT

The phe­nom­e­non won’t af­fect the on­set of mon­soon or pre-mon­soon show­ers, say met depart­ment of­fi­cials. Once the mon­soon cur­rent picks up speed, cool east­erly winds will push the west­erly winds away. Re­lief is ex­pected around June 17.
